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
