gmp_xor

(PHP 4 >= 4.0.4, PHP 5, PHP 7, PHP 8)

gmp_xor — Bitwise XOR

Description

gmp_xor(GMP|int|string $num1, GMP|int|string $num2): GMP

Calculates bitwise exclusive OR (XOR) of two GMP numbers.

Parameters

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).

Return Values

A GMP object.

Examples

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
