Warning

This function has been DEPRECATED as of PHP 7.2.0, and REMOVED as of PHP 8.0.0. Relying on this function is highly discouraged.

Description

gmp_random(int $limiter = 20): GMP

Generate a random number. The number will be between 0 and (2 ** n) - 1, where n is the number of bits per limb multiplied by limiter. If limiter is negative, negative numbers are generated.

A limb is an internal GMP mechanism. The number of bits in a limb is not static, and can vary from system to system. Generally, the number of bits in a limb is either 32 or 64, but this is not guaranteed.

Parameters

limiter

The limiter.

A GMP object, an int or a numeric string.

Return Values

A random GMP number.

Examples

Example #1 gmp_random() example

<?php
$rand1 
gmp_random(1); // random number from 0 to 1 * bits per limb
$rand2 gmp_random(2); // random number from 0 to 2 * bits per limb

echo gmp_strval($rand1) . "\n";
echo 
gmp_strval($rand2) . "\n";
?>

The above example will output:
