PHP Bitwise Operators - PHP Tutorial 34

Notes for You:: PHP Bitwise Operators - PHP Tutorial 34
are used to perform operations on bits.
Bitwise operators convert the given decimal number(s) to their binary equivalent number, and then they perform the operation on those bits and return the result in the form of decimal.
&: Bitwise And operator:
If both LHS and RHS operands are 1 then the result will be 1, in all other cases result will be 0.
|: Bitwise Or operator:
If both LHS and RHS operands are 0 then the result will be 0, in all other cases result will be 1.
^: Bitwise Exclusive Or operator:
If both LHS and RHS operands are same bits then the result will be 0, otherwise the result will be 1.
~: Bitwise complement operator:
Add 1 to the given number and change the sign.
<<: Bitwise Left Shift operator:
Shifts the bits of first number to the left by number of positions indicated by second number.
firstNumber * pow(2,secondNumber).
>>: Bitwise Right Shift operator:
Shifts the bits of first number to the right by number of positions indicates by second number.
firstNumber / pow(2,secondNumber).
Example Code:
echo 1 & 1,"<br/>"; //1
echo 2 & 5,"<br/>"; // 0
echo "<br/>";
echo 1 | 1,"<br/>"; //1
echo 2 | 5,"<br/>"; // 7
echo "<br/>";
echo 1 ^ 1,"<br/>"; //0
echo 2 ^ 5,"<br/>"; // 7
echo "<br/>";
echo ~3,"<br/>"; //-4
echo ~(-3),"<br/>"; //2
echo "<br/>";
echo 1<<4,"<br/>"; // 16
echo 12<<2,"<br/>"; // 48
echo "<br/>";
echo 16>>4,"<br/>"; // 1
echo 48>>2,"<br/>"; // 12

Very impressive, but will happen if i write something like: 011 & 11? for some reasons its different than 11 & 11

Note:
if you prefix 0 to a number it is considered as octal number , not as decimal number so you find the difference in the output
