What is the gmp_xor() function in PHP?

Overview

The gmp_xor() function in PHP is used to find the bitwise XOR of the given two numbers.

Note: You can learn more about the bitwise XOR operator here.

Syntax

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

Parameters

  • num1: This is a GMP object, integer, or a string.
  • num2: This is a GMP object, integer, or a string.

Return value

The method returns the bitwise XOR of num1 and num2.

Code

<?php
$num1 = gmp_init(5);
$num2 = gmp_init(3);
$xor = gmp_xor($num1, $num2);
print "5 ^ 3 = ".$xor;
?>

Explanation

  • Line 2: We define num1.
  • Line 3: We define num2.
  • Line 4: We calculate the XOR of num1 and num2 using the gmp_xor() method.
  • Line 5: We print the bitwise XOR result.
