I didn't understand OOP in my first language and i understand this so easily with you , The issue is not in the language or the difficulty of the topic or my mind. I think it is in the simplicity of the style and the conscience of the person who explains. Thank you for your great effort.❤❤❤
I'm so glad I found your page! You're helping a lot with your clear explanations. The best teachers are those who put themselves in the shoes of total beginners, and you're doing it so well.
Dani has a gift of making the difficult and challenging seem so easy. This is one of the, if not the best OOP tutorials on the planet. Thank you for sharing your knowledge in the subject area. Look forward to more tutorials.
I couldn't possibly thank you enough for this video. The way nothing goes unsaid is remarkable in helping me understand every point without question! You are the best teacher I have come across yet!!
I finished this playlist, and I'm so glad. PHP is very much the same as Javascript and others; it's just different to write. Thank you so much for sharing the knowledge.
I don't understand why this video has only 20k views. It's a free and great course. Maybe this language isn't that popular, and I made a mistake learning it. I hope I'm on the right web development path.
I learned a lot from you, mmtut, back in 2016/17/18 when I started Web Development. Your tutorials helped me with all the fundamentals of designing website and building PHP websites. Even though I'm more of a JavaScript developer now, but I do miss your tutorials a lot. So happy to see your tutorial again. I'll definitely give some attention to PHP again so I'll build up my skills in PHP again and then move to Laravel. It would be great if you could do some advance tutorials on Laravel for PHP developers in your channel. Thank you so much for your tutorials and inspirations and all I learned from you. If I'm proud to be good in Web Development today, you helped set me up for who I'm today. Thank you and God bless you, Dani Crossing.
Glad to have you back on coding tutorials. Best TH-camr out there for anyone who wants to learn about coding and security at the same time. I love mmtuts 😅
Yet another fantasitc video, i've looked at a lot of other videos for learning PHP, in particular OOP and how I can apply what I already know with proceedule PHP and re-factoring my code into OOP. Your style of teaching is amazing and for me makes much more sense, thank you :-)
I watched your video, tutorial, about OOP and for the first time everything, from 1st sec till the last is crystall clear and easy to understand. Hope you make more videos and tutorials. Thank you!
Excellent video. I pray that you will create a Laravel tutorial, and if it happens, I'm thrilled. Thank you once more for your tutorials, Dani. I gain a lot of knowledge. MABUHAY ka meaning I SALUTE you in filipino.
Hi Dani! It's amazing how you keep improving the video series you already made, by making them again completely!🤯 I was wandering if you maby like to make a forgotten password system with OOP in the future? 😁 Have a nice weekend!
This is such an awesome video. You don't just have the coding skills, but the communication skills as well. You approach from my vantage point -- procedural style. Then you show the differences, giving the how and why. Thank you for helping me finally start wrapping my head around OOP!
What kind of teacher you are ?! Thanks a lot for your efforts. Please make a Laravel Playlist if possible: It will be a fantastic journey for your subscribers and fans like me. (I sometimes click ads on your videos intentionally as a small sign of gratitude for what you are delivering. This is the minimum thing I can do :)
I love so much Danny. Thanks for your videos. We've been doing a lot of log in systems and Its almost like that's the only thing to do with PHP. Please can you do more projects with PHP this time
Hello Dani, I learned to use the MVC model with your tutorials a couple of years ago, I appreciate everything you teach in your videos, there is something that I could never do on my own and I researched it a lot but I can't find a way to do it. Using OOP and MVC, how do I ensure that a function that performs an INSERT in the database returns the ID of that INSERT? I tried every way to use lastInsertId but it doesn't work for me. Could you give me a hand with that? thank you.
Hey! As i can see you get a desk that can adjust its height. Im beginning to study informatics and also im gaming alot and just wanted to ask you, if you could recommand a desk? Because also im moving out and im gonna get a fresh setup anyways :D Would you say those desks are worth their money?
Thank you so much! Making PHP easier. May I draw the conclusion; a login-systeem with OOP is safer way than with procedural PHP? Or just an other way to do it?
I applied to PHP developer, even though I don't have lot of PHP knowledge, and they got back to me from the company. So I started learning from your tutorials and it helped me so much! THANK YOU! I have 1 question about OOP Encapsulation. How by using PUBLIC getters and setters I am hiding data from the user? He can just use the getter and the setter to change private fields in the class. 😬
The user can’t access anything unless we allow them to 🙂 that’s why we use PHP, since it is a server side language, meaning the user can’t access the code. The reason we use getter and setters, are for our own benefits as the developer, since it allow us to have more control over how we get and set fields 🙂 not for the sake of the user.
Hey Dani! I wrote a series of codes years ago using functions instead of classes, and that's a habit I kept. In terms of speed (execution) which is the best route? Functions or Classes? Thanks for what you do!
Functions are faster because it involves less encapsulation, however you need to consider the purpose of your code rather than speed, when we talk about "when to use classes or functions". For example, if you need something like a login feature, then because of the scale/size of that feature, it is better off to use classes. However if you just need a simple feature to show the current time on your website, then it would be overkill to use classes. So it's not about "if you should use classes or functions". It's about "what tools best suits the task". 🙂 I see too many PHP developers argue about "Procedural vs OOP", and they all completely miss the point. It's like arguing about "if a screwdriver or a drill is the better tool", which is silly since they each have their uses.
@@Dani_Krossing Excellent. I basically use functions with APIs and Curl so I will not touch them then. I was asking about "execution speed" because I mostly interact with trading platforms, which require excecutions to be as minimal as possible :) Thanks again, Dani!
In the futur you create tutorial for Laravel or Symfony for learn the next step in OOP PHP ? And thank's for you video :) It's perfect for understand the base of OOP simply. When a for advanced OOP ?
Why does my compiler not accept this attempt? It says dont use place holders on public functions. It's considered instantiating the same function again
please do not advise me, I am trying to make bones for a character in unity with a PNG image in the skinning editor, but when I try to move with them or adjust the structure of the body in edit geometry, copying starts as soon as I press the mouse.
The amount of code that OOP can save is very high when citing generic classes and inheriting to more specific classes. That being said, there is a maintenance price for inheritance and polymorphism.
"Hi Dani, I trust you're doing well. I've been working on developing a PHP script and I want to ask you something. I'm interested in implementing a server-side activation mechanism to ensure that users need to interact with my website or server before the script can be fully activated and used. Additionally, I want to make it challenging for users to modify or bypass the activation mechanism and ensure that I have remote control over the activation process. Could you please provide guidance on how I can build such a mechanism? Specifically, I'm looking for advice on: 1. Implementing the activation logic within the PHP script. 2. Enhancing security measures to prevent unauthorized modifications or bypassing of the activation mechanism. 3. Establishing remote control over the activation process to enable/disable script functionality as needed. Thank you in advance for your help!
It’s because signupUser() needs to be accessed from a normal PHP file, when creating the object. 🙂 Protected we use, when only parent classes should have access to the method. So “a class accessing methods from another class”.

Procedural is great for smaller PHP features on a website, however the more complex a website gets, the more complex and less scalable it gets if you use Procedural PHP. 🙂 It is only early on, that Procedural appear “less complex”, until the moment the developer stands with a more complex website in front of them. 😊 At that moment, OOP is worth doing since it makes the code more structured. So while OOP makes the code itself more complex, the overall project becomes less complex through the usage of OOP. Additionally, if you plan to work with PHP in any professional capacity, then OOP PHP becomes mandatory, since frameworks tend to use OOP.
i wish u wouldve provided some better examples to which OOP is better suited. the sign up example that u provided is essentially procedural code inside an object, which seems redundant or like unnecessary complexity
Always remember that a 'method' is not a function and it is written: function name(); You can see at a glance that it is NOT a function. I hope that is all clear now.

Dani should you use the getter and setter methods within the constructor?
No you can just assign the data directly to the properties 🙂
Actually you should use setters in the constructor if you have validation in the setters.
I notice when you say PHP, you say PSP and, when you say fields, you say feels.
Just something funny. Thanks for the vids!
