What is the significance of ‘^’ in PHP?
The ‘^’ is a bitwise operator in PHP, i.e XOR (exclusive OR) bitwise operator, that is used to display the ASCII values of variables in question. For example − For evert bit in the value, the ^ operator checks if that bit is the same in the other value too. If the values are same, 0 is produced as an output, otherwise 1 is shown as output. Below is an example illustrating the same −
Example
Live Demo
<?php
$x = "a";
$y = "b";
$x ^= $y;
$y ^= $x;
$x ^= $y;
echo $x;
echo "\n";
echo $y;
?>
Output
b
a
Different variables are assigned character values and the ‘^’ operator is used to perform XOR on the two variables. Relevant output is displayed on the console.
