Bitwise Operators
Bitwise Operators
Bitwise operators allow you to turn specific bits within an integer
on or off. If both the left- and right-hand parameters are strings, the bitwise
operator will operate on the characters in this string.
Bitwise operators in PHP is similar to the bitwise operator in C &
C++.
Example:
echo 12 ^ 9; // Outputs ‘5′
echo “12″ ^ “9″; // Outputs the Backspace character (ascii 
// (’1′ (ascii 49)) ^ (’9′ (ascii 57)) = #8
echo “hallo” ^ “hello”; // Outputs the ascii values #0 #4 #0 #0 #0
// ‘a’ ^ ‘e’ = #4
