hi derek i just started learning php and mysq. i have question on php and mysql coding. can i email you the code to you could tell me what i did wrong. I don't know how to fix the error. much appreciated 🙏
11:00-11:03 best programmer quote of the year. I enjoy your videos though, best i could find on youtube for my tastes, hope you don't quit anytime soon. In general, great work!
You're the first tut video maker I've seen that doesn't take forever to spit the words out, or constantly digress with side-thoughts. You effortlessly compacted an enormous amount of info into this vid, in record time. Thanks Derek I now have an almost complete understanding of classes & objects!
I can not stress enough how much this has helped. I am a long time PHP coder who has always had a mental block with classes OOC. This will help greatly in me writing more secure code, using less variables being passed in the URL.
I came from the plain old procedural PHP programming and had been struggling to find a decent tut to make me understand OOP design and this is far the best tut i ever found on the internet. Thank you! Subscribed.
btw, if I may suggest, can you pursue this series by adding OOP PHP-MySQL tutorial video. I honestly want to know how would OOP design be considered once you will need to have the interaction with database. Should there be a class for all sql query? something like that maybe?
Watched this again for a review as I get deeper into Wordpress. All of the unsure things of php were already all explained here. Thanks for making such a compact and info-rich videos.
Fantastic! I absolutely love the way you present information and the speed of your videos! Please do NOT change! I understand that those who are not familiar with the terminology will find it difficult to follow, but once you have progressed beyond that stage it can get so tiring and time-consuming to wade through these basics in order to get the real information. Your videos are like a breath of fresh air. Thank you.
Hello Derek.. I just want to personally thank you for creating quality videos about programming and stuff that are relevant to it. This way we can learn from your videos without paying and going to school. Hopefully, we can pay it forward to many people in the future. Thank you very much! :)
Derek, not only Your tutorials are extremely efficient and professional, but i love the mood You are presenting it all with. Some kind of a funny sarcastic comedy type positive voice that makes it feel as if everything is easier than it seems and so it puts my mind in a way that it is fun to learn and makes me hungry for this knowledge. Thank You so much, i hope You are getting at least something out of these videos, because what You give us is priceless. Big fan and a learner from Lithuania! :)
I honestly feel that Derek has helped change the face of the internet. He is teaching and inspiring the developers of today to develop the internet for tomorrow. Bravo.
Thank you for the very nice compliment :) Wow, that was very nice. I hope that I have been able to help. I'm very lucky to be in the position to do this.
I have been programming in php in a functional style, not OOP. This tutorial really filled in a lot of gaps that I did not understand before. Thank you!!!
Thank you so much for this! This is the best, most coherent and comprehensive tutorial on php classes I have been able to find! I finally understand so much more and see possibilities and flexibility where I was once confused. I will be watching more of your tutorials! Thank you!
Your tuts are to the point and does not waste time with all kinds of rubbish info or slow typing and you don't waste time. Your tut videos are AWESOME, keep up the GREAT work !.
Like any other PHP static variable, static properties may only be initialized using a literal or constant before PHP 5.6; expressions are not allowed. In PHP 5.6 and later, the same rules apply as const expressions: some limited expressions are possible, provided they can be evaluated at compile time.
Irakli Khakhviashvili speed is fine. This is the best thing about Derek Banas . He keeps it fast so viewers wont get bored. And you always have a "Replay" Option. Dont want to be a jerk, but all i am saying is Speed is fine. Its perfect!
This seems like a great video for someone who already has some knowledge about coding and not for beginners... but since I belong to the first group THANKS!!
You are awesome. I thought to subscribe in the middle of this video specifically but guess what I already have your channel subscription. Thank you for such a cool video. It's like easing out pain and putting me in a situation to know more PHP OOP.
Just coming back to my original PHP tutorials I followed a while ago. Thanks Derek for making these videos! I'm now a Web developer and it all started from these videos. marcus
I love this video because I already have knowledge of Classes in other programming language, and I just needed a summary of it in PHP. This makes it so easy to compare and translate from one to another. Awesome Video! Thank you!
Definition: An object is a software bundle of variables and related methods. Note : Before watching this videos I have wrote the following example hoping I am right. $somevariable = new SomeClass(); // probably the protected variables inside class called attributes? // and here $somevariable is // an object of SomeClass() echo $somevariable - > functionInsideSomeClass(); // functionInsideSomeClass(); have to return something to display
WOW that was a bunch of information in 26 minutes! You are good! I am a beginer so I will need to watch this a couple of times. Thanks for the tutorial, dude!
Hi Derek, I am absolute fan of yours and I think you have the most perfect & impressive voice for these tutorials. I follow your tutorials and just love your explanations. I would be most glad to see a tutorial on php exception handling with their actual implementation in websites.Now while there are many tutorials on that, one from you would be the best. I would particularly like to see how to implement / display an error page that is displayed every time an error occurs and display those errors keeping in mind whether it is running in the design or production mode. Thanks and I really hope you will consider to do this tutorial soon. Thank you.
I would like to see videos that break down the concept of object programming, so that I could take in one concept at a time in small steps. The first part of this video is easy to understand. When it gets complicated, I can't grasp any of the concepts. It would help to go in depth on every concept, one at a time. Thank you.
I really like your videos, man ! I learnt lots of things in your videos instead of my college course in a short period of time ! Thank you very much for sharing your knowledge !
20:00 - Another example of polymorphism is where we're going to be able to define functions that are going to be able to accept classes that extends a specific class or a specific interface I had to write this down man xD
Derek Banas I like you even more that you took the time to respond to me.... I am a new developer that came from a CAD/CAM background.... Crazy eh? Here is something I made as a CAD person, but only for fun..... scontent-a-iad.xx.fbcdn.net/hphotos-xap1/t31.0-8/1400593_10200845606214754_1716709710_o.jpg
Note: The oop tutorials are based in real objects with solid examples, the real life in programation is very abstract and most times you have to think strange way, is normal.
Could you make a small video covering PHP Namespaces, anonymous functions, traits? Especially traits and namespaces are topics that I have struggled with.
He's a genius yer man Derek, brill vid, brill tutorial, well worth checking out the links, rewrite the code line by line and try to understand it. One of the best channels on youTube
Hey Derek, this helped me, thank you so much! :) One request though, could you please show abstract classes in action? And does every method and attribute in an abstract class need the keyword 'abstract' before it?
Nice summary of the basics of OOPHP. Next time: namespaces, auto-loading, package management, reflection classes? In stead of using a switch to detect whether a property exist, you could try using property_exists($this, $name) (php.net/manual/en/function.property-exists.php). This way, you would not need to change the switch statement every time you change/add/delete a property. Making your code more concise and maintainable.
Rotharius Thank you :) Yes I made a judgement call there on whether to use that method or switch. I probably should have shown both. Thank you for the input
I understand why you did it; to keep things simple for newcomers to OOPHP and not scare them off with all these new scary functions. Perhaps some inspiration for a more in-depth tutorial on OOPHP? ;) Anyway, thanks for the video.
Derek Banas I think it would be very helpful to do this for web novices who would like to set up their own site and need something more advanced than just how to do HTML+CSS+PHP. I'm thinking more like a start-to-finish series on setting up your own site w/hosting, DB, scripts, cron jobs etc.
Very Very Usefull Video. I ll rrcomend this video to any programmer i know not yet impementing OOP and even to those about to learn programming . This is a mist see before they start writing their first code
If you are interested in OOP I recommend looking into the SOLID principles and listening to uncle bob lectures. This channel also has a great section on design patterns that are a pretty cool thing to fill your developer tool box with ;)
@Darek. After my first love. this is first time i have this feeling of love you for your video. I just pose video and came here to comment. your video did trick that 4 hours of lynda training could not do. Love your video bro
Awesome video - Thank you for putting it together. I have one question, Something I'm not able to wrap my head around yet is the "this->name" thing. Could you expand on that a bit further? Kind Regards
+AlAndalus Thank you :) When you create a class you need a way of referring to the object. Since the class is made before the object you can't refer to it by name so you refer to it with the default this.
I still have no idea how this could be useful in like making a Webshop or a hotel room reserving website. What are the benefits of OO instead of just using SQL while loops etc?
The benefit is mainly that you can much better organize your code by dividing it into meaningful sections more closely related to the way the concepts they describe are organized in the real life. By writing your code this way, you can also avoid code duplication by interacting between those parts more efficently, thus increasing performance and letting you more easily maintain your application and add new functionnalities to it over time. For example, you could create a Customer class, from wich an object $customer is created each time you get a new customer, automatically assigning him a name, an age, a salary, etc. through the constructor method of this class, and incrementing the value of a static variable $totalNumberOfCustomers by one in this case, and decreasing it through the destructor method if the customer never came back after several years.... And you could create a mother class Room, and several daughter classes LittleRoom, AverageRoom and BigRoom that would each inherit commun properties from the Room class, but still defining each one different values for those. That kind of stuff...
Derek, coming from C# and JS, I feel like I already know PHP. I love PHP's logical function/method names... One of the things I hate about JS is the pop() push() shift() crap. I actually studied PHP 3 when I was like 12... Has there been a lot of change since? Its hard for me to remember.
Hi Derek! Thanks for all your great tutorials. I was watching this one and following along in my computer. I ran into some differences and wonder what it could be due to. When I have a method in a class with a echo line and then I create the class and then call the method, I don't get the echo showing in my chrome web browser. I can see it is working as I can return something in the method and that will display, but any echo lines I put in the method do not display. Any thoughts why this would be? In your example you have the magic method __get echo "Asked for" . $name . ""; If I do this and call the get method it returns the name, but does not print the echo line (ex. Asked for sound).
This is an awesome tutorial. But I think it's quite confusing that you use the variable $name as the animal name, and then again as the variable within __set and __get - why not use __set($var, $value) or something like that so it's extra clear it has nothing to do with the "name" of the animal you specified.
It was really good again! I'm waiting the continuation with namespaces, EventListener or something :) But I have a question: Why do you use snake case instead of CamleCase? Is there any reason or habit? IMO the CamelCase more frequent in the PHP.
Hi Derek, I just wanted to say that you are the best, You made this so much fun and easy, I want to thank you for that plus I want to request you that can you please make some videos on plugin/theme development for CMS such as joomla or wordpress.
charlie curtid Hi Charlie, Thank you for the compliment :) I actually made about 80 tutorials on Wordpress here www.newthinktank.com/videos/web-programming/wordpress-how-to/
Good explanation sir, I followed all your videos here thanks. By the way, may you include tutorials about data encapsulation I thought you did not include that in this video. Thank you very much sir.
Hey Derek great tutorial, I had a question regarding the __get and __set magic methods. Is it more desirable to use getter and setter magic methods or define your own custom getters and setters?
Hey derek great video! I have a request in regards to php. Can you make a video about how to make a login screen, more specifically like if a user has to be a pro member to view specific items and if they are not pro they will see a page with limited items and limited functionality etc
I'm happy to be able to help :) Yes I've been a programmer for 30 years. I've worked at Apple, in financial services, web development, etc. I currently mainly make shopping carts and mobile apps
Your last PHP Programming video was very clear, despite the fact that it was very fast paced. But this video was way too complicated for me. I am a total beginner in PHP and I wanted to understand object programming, but I got lost at the subclass part. It is just too hard to comprehend.

This is why i hate college... these two php videos would take months to learn in school and cost a $hit ton of $$$...
ProgramThis! Thank you :) I'm doing my best to make education available for free.
Derek Banas The world of education is slowly changing for the better... And it's all thanks to people like you and videos like these.
Your Videos are great.... Thank You! May God Bless You!
so true
+Derek Banas that is so noble task. We need more people like you in the world! Keep the good work going! :)
One of the best OOP tutorial I've seen, thanks a lot!
Thank you very much :)
Been with you since the first week. You are a savage my man Mr. Banas.
Your tuts are to the point and does not waste time with all kinds of rubbish info or slow typing and you don't waste time. Your tut videos are AWESOME, keep up the GREAT work !.

Great video! This quick and generalized style of teaching is exactly what works for me. Now I just need one for Doctrine ORM and Symfony.
Happy I could help :) I'll see what I can do about the requests
Irakli Khakhviashvili speed is fine.
This is the best thing about Derek Banas . He keeps it fast so viewers wont get bored.
And you always have a "Replay" Option.

Thank you for the compliment :) I do my best
This seems like a great video for someone who already has some knowledge about coding and not for beginners... but since I belong to the first group THANKS!!
You're welcome :) Yes it is for people that have experience in programming other languages.

That's awesome!!! Congratulations on your job :)
The thing you do, starting with an visual and simple example of the subject, is what makes this video better than the others. Thank you :-)
+Kristine Helms Thank you very much for the compliment :)

Note : Before watching this videos I have wrote the following example hoping I am right.
$somevariable = new SomeClass(); // probably the protected variables inside class called attributes?
// and here $somevariable is
// an object of SomeClass()
echo $somevariable - > functionInsideSomeClass(); // functionInsideSomeClass(); have to return something to display
with all the programming languages I've learned, I have never really understood how it works and where its needed, but now I do, thanks so much!
Thank you :) I'm very happy it helped
Very very useful tutorial. Someone who haven't know OOP yet should watch this to learn. It's pefect.
+Patryk Wojciechowski Thank you for the very nice compliment :)
WOW that was a bunch of information in 26 minutes! You are good! I am a beginer so I will need to watch this a couple of times. Thanks for the tutorial, dude!
Thank you very much :) When I promise something in the title I do my best to meet it
Hi Derek, I'm glad to say you I'm learning a lot of programming just watching your videos. Thank you very much!
Hi Derek, I am absolute fan of yours and I think you have the most perfect & impressive voice for these tutorials. I follow your tutorials and just love your explanations.

Hi Derek, Thanks for the reply and looking forward to seeing you there soon !
I am completely new to JAVA. Your videos are really amazing & BEST IN THE WORLD and they are helping me a lot. Thank you soooo much.
Princess Gohar Thank you for the nice compliment :) You're very welcome
Instead of:
function __set($attribute, $value)
{
switch ($attribute) {
case type:
$this->type = $value;
break;
case name:
$this->name = $value;
break;
case age:
$this->age = $value;
break;
default:
echo $attribute . " not found ";
}
}
you can do:
function __set($attribute, $value)
{
$this->$attribute = $value;
}
That's what I call - fast paced tutorial.
Derek your videos are the best.
Thank you very much :)
For me this was a very good synopsis of PHP OOP. Thanks.
Thank you :) I'm glad you liked it
Love the :-( in the destructor. Its sooo nice
Thanks, very good overview of what PHP provides for OOD, JIm
+freightuk Thank you :)
This is great for a procedural programmer like me that needs to work in a OOP environment. Thanks a million. This helped a lot.
Johan Potgieter You're very welcome :)
I would like to see videos that break down the concept of object programming, so that I could take in one concept at a time in small steps. The first part of this video is easy to understand. When it gets complicated, I can't grasp any of the concepts. It would help to go in depth on every concept, one at a time. Thank you.
Am I seeing something? Class constants use "const" and Classless constant use "define" but why?
PHP is weird
Love it. Compact, concise and complete. Very refreshing and easy to follow.
If you're a C# or Java programmer who knows some typescript... set this bad boy to 2x play speed and you'll know OO PHP in 15 minutes.
+Brett Fleming Thank you :)
I really like your videos, man ! I learnt lots of things in your videos instead of my college course in a short period of time ! Thank you very much for sharing your knowledge !
Mauricio Ferreira Thank you :) I'm very happy that I could help.
wow, i literally learned php and mySQL in 2 hours :D (since i can program in C and C++ this was everything needed), thak you so much
I'm very happy that I could help :)
You forgot to realise the future of PHP and include a tutorial on traits for better PHP OOP
20:00 - Another example of polymorphism is
where we're going to be able to define functions
that are going to be able to accept classes
that extends a specific class or a specific interface
I had to write this down man xD
Sorry if I made that to complicated. I try to use normal words most of the time
I love your vids! I love the fact that you pump out a $h!+ load of information in a short period of time....
Thank you soooooo much!
Matt Dixon Thank you :) I did my best to make original videos. I'm glad you like them.

Matt Dixon Nice!
Also at 0:46 he say "He may have an ARRAY of ties, shirts, pants, and shoes."
Well if he say an ARRAY as we thought the ARRAY as a variable ?
Note: The oop tutorials are based in real objects with solid examples, the real life in programation is very abstract and most times you have to think strange way, is normal.
I love these one video series so much! this is a fantastic channel!
ProgramThis! Thank you :) Rails are coming next.
I love this Tutorial. In a way if the person who is watching this already read some info about OOP PHP.
Thank you :) I'm glad it helped
Your videos are pure Gold
Thank you :) I try to do my best
Very useful refresher. I'd like to see you cover Cakephp too.
+Russell Dicken Thank you :) It is on the list
Could you make a small video covering PHP Namespaces, anonymous functions, traits? Especially traits and namespaces are topics that I have struggled with.
+ITWarrior I'll see what I can do. Thank you for the request.
He's a genius yer man Derek, brill vid, brill tutorial, well worth checking out the links, rewrite the code line by line and try to understand it. One of the best channels on youTube

You should try Brackets an Open Source software from Adobe actively being contributed to by many people.
Hey Derek, this helped me, thank you so much! :)
One request though, could you please show abstract classes in action? And does every method and attribute in an abstract class need the keyword 'abstract' before it?
I love you! you always keep me way more advanced than my classes !
Thank you :) I'm very happy to be able to help
Nice summary of the basics of OOPHP. Next time: namespaces, auto-loading, package management, reflection classes?
In stead of using a switch to detect whether a property exist, you could try using property_exists($this, $name) (php.net/manual/en/function.property-exists.php). This way, you would not need to change the switch statement every time you change/add/delete a property. Making your code more concise and maintainable.
Rotharius Thank you :) Yes I made a judgement call there on whether to use that method or switch. I probably should have shown both. Thank you for the input
I understand why you did it; to keep things simple for newcomers to OOPHP and not scare them off with all these new scary functions. Perhaps some inspiration for a more in-depth tutorial on OOPHP? ;)
Anyway, thanks for the video.
Thanks for this tutorial Derek! It was really useful as a quick review of php for work. Keep up the great work!
Thank you very much :) I'm happy I could help
Your teaching method is unique and interesting. I loved it 😃😄😃😄😆💐 thanks soo much n keep making these wonderful videos 💐💐
Thank you for the compliment :) I'm happy I could help
Fantastic video! It would be awesome if you could cover databases, web services, and apps backed. Thank you
Tchadry I always planned on making a video like this for web services next. I may see if I can cover most everything about PHP and MySQL in one video
Derek Banas I think it would be very helpful to do this for web novices who would like to set up their own site and need something more advanced than just how to do HTML+CSS+PHP. I'm thinking more like a start-to-finish series on setting up your own site w/hosting, DB, scripts, cron jobs etc.
bas3q I'll cover SQL next
Derek Banas Sweet, thank you!
Very Very Usefull Video. I ll rrcomend this video to any programmer i know not yet impementing OOP and even to those about to learn programming . This is a mist see before they start writing their first code
Thank you for the compliment :)
If you are interested in OOP I recommend looking into the SOLID principles and listening to uncle bob lectures. This channel also has a great section on design patterns that are a pretty cool thing to fill your developer tool box with ;)
why did you tell something, without showing the way which will be usefulll for????
Spot sings: "Boww woow wooow Grover is being destroyed". Haha, I have never saw such an evil dog :D #PeaceForGrover
@Darek. After my first love. this is first time i have this feeling of love you for your video. I just pose video and came here to comment. your video did trick that 4 hours of lynda training could not do. Love your video bro
+Salim Kotadiya Thank you for the kind compliment :) I'm happy that you enjoyed it.
Simple, easy to understand, all most power but you need to know are well stated
Thanx a lot. I have learnt a lot. It's quite easy if you already know another OOP Language.
I'm happy I could help :)
I just had to sub once I heard Wordpress as that's what I mainly develop for. Thanks a lot Derek, much appreciated.
Thank you :) Most of my sites are WP sites as well
i am phper in china, my english weak, but i understand your lession, so interesting~~ i like it.
thx~
Thank you :) I'm happy the video helped
Awesome video - Thank you for putting it together. I have one question, Something I'm not able to wrap my head around yet is the "this->name" thing. Could you expand on that a bit further? Kind Regards
+AlAndalus Thank you :) When you create a class you need a way of referring to the object. Since the class is made before the object you can't refer to it by name so you refer to it with the default this.
I still have no idea how this could be useful in like making a Webshop or a hotel room reserving website. What are the benefits of OO instead of just using SQL while loops etc?
The benefit is mainly that you can much better organize your code by dividing it into meaningful sections more closely related to the way the concepts they describe are organized in the real life.
By writing your code this way, you can also avoid code duplication by interacting between those parts more efficently, thus increasing performance and letting you more easily maintain your application and add new functionnalities to it over time.
For example, you could create a Customer class, from wich an object $customer is created each time you get a new customer, automatically assigning him a name, an age, a salary, etc. through the constructor method of this class, and incrementing the value of a static variable $totalNumberOfCustomers by one in this case, and decreasing it through the destructor method if the customer never came back after several years.... And you could create a mother class Room, and several daughter classes LittleRoom, AverageRoom and BigRoom that would each inherit commun properties from the Room class, but still defining each one different values for those. That kind of stuff...
Another Amazing Tutorial By Derek Banas!
***** Thank you :) I promised it was coming.
Derek, coming from C# and JS, I feel like I already know PHP. I love PHP's logical function/method names... One of the things I hate about JS is the pop() push() shift() crap.
I actually studied PHP 3 when I was like 12... Has there been a lot of change since? Its hard for me to remember.
I love PHP as well. Yes there have been quite a lot of changes. It is a constantly evolving language.
Best tutorial on this I've seen!
Thank you I'm happy it helped :)
This is how all classes should be after you get past Data Structures and Algorithms.
Thank you :)
very nice example, solved all my questions. Thank you very much
+Yuchen Zhou Thank you :) I'm glad it helped.
Hi Derek! Thanks for all your great tutorials. I was watching this one and following along in my computer. I ran into some differences and wonder what it could be due to. When I have a method in a class with a echo line and then I create the class and then call the method, I don't get the echo showing in my chrome web browser. I can see it is working as I can return something in the method and that will display, but any echo lines I put in the method do not display. Any thoughts why this would be? In your example you have the magic method __get echo "Asked for" . $name . ""; If I do this and call the get method it returns the name, but does not print the echo line (ex. Asked for sound).
hmm.... I can't accept calling a static variable with object
knowledgeable. really different way of exhibiting everything in a short time
This is an awesome tutorial. But I think it's quite confusing that you use the variable $name as the animal name, and then again as the variable within __set and __get - why not use __set($var, $value) or something like that so it's extra clear it has nothing to do with the "name" of the animal you specified.
It was really good again! I'm waiting the continuation with namespaces, EventListener or something :)
But I have a question:
Why do you use snake case instead of CamleCase? Is there any reason or habit? IMO the CamelCase more frequent in the PHP.
Árpád Belovai I'm not biased towards any naming conventions. Since I normally consult I use what ever the organization prefers.
what a great roller coaster of oop tut. to follow this is!
Thank you very much :)
Hi Derek, I just wanted to say that you are the best, You made this so much fun and easy, I want to thank you for that plus I want to request you that can you please make some videos on plugin/theme development for CMS such as joomla or wordpress.
charlie curtid Hi Charlie, Thank you for the compliment :) I actually made about 80 tutorials on Wordpress here www.newthinktank.com/videos/web-programming/wordpress-how-to/
You did it again, sir!
Excelent video!
* Applause *
TheSkogemann Thank you :) I'm glad everyone seems to like these
Good explanation sir, I followed all your videos here thanks. By the way, may you include tutorials about data encapsulation I thought you did not include that in this video. Thank you very much sir.
Hi Derek. I would love to see a Django video, unless it's lurking somewhere in one of your many Python tutorials. Keep up the awesome work!
Thank you :) Django is coming after I cover PyQt and Kivy.
This is a great explanation of OOP in any language! Great video. :)
Scott Allen Thank you :)
soo awesome Derek! Thank you :-) Love to see a longer more in-depth version of this? more OOP PHP please?
Imran Ashraf Thank you :) I'll be making PHP framework tutorials very soon. Laravel will come first.
Derek Banas You are awesome :) But sometimes I get confused, so I just have to learn more :)
Hey Derek great tutorial,
I had a question regarding the __get and __set magic methods. Is it more desirable to use getter and setter magic methods or define your own custom getters and setters?
Ryan Schurton It depends only on if you must do any special checking on the data or not.
Hey derek great video! I have a request in regards to php. Can you make a video about how to make a login screen, more specifically like if a user has to be a pro member to view specific items and if they are not pro they will see a page with limited items and limited functionality etc
Fan-freaking-tastic. 10/10. Or 5/7 whichever praise you prefer.
+Matt Noxon Thank you very much :)
Thanks Derek! Really nice fast track to PHP OOP!
Thank you :)
traits
where are they
Hey Derek, thanks so much. You know a lot of things, what did you study? Did you have a career as a developer?
I'm happy to be able to help :) Yes I've been a programmer for 30 years. I've worked at Apple, in financial services, web development, etc. I currently mainly make shopping carts and mobile apps
Just too good, you really explain to my understanding
Thank you very much :)
Your last PHP Programming video was very clear, despite the
fact that it was very fast paced. But this video was way too complicated for
me. I am a total beginner in PHP and I wanted to understand object programming,
but I got lost at the subclass part. It is just too hard to comprehend.
Well done! Great tutorial: complete, yet condensed.
Eduard Fornés i Català Thank you :)
