gmp_xor — Bitwise XOR
Calculates bitwise exclusive OR (XOR) of two GMP numbers.
num1
A GMP object, an int,
or a string that can be interpreted as a number following the same logic
as if the string was used in gmp_init() with automatic
base detection (i.e. when base is equal to 0).
num2
A GMP object, an int,
or a string that can be interpreted as a number following the same logic
as if the string was used in gmp_init() with automatic
base detection (i.e. when base is equal to 0).
A GMP object.
Example #1 gmp_xor() example
<?php
$xor1 = gmp_init("1101101110011101", 2);
$xor2 = gmp_init("0110011001011001", 2);
$xor3 = gmp_xor($xor1, $xor2);
echo gmp_strval($xor3, 2) . "\n";
?>The above example will output:
1011110111000100
