gmp_random
(PHP 4 >= 4.0.4, PHP 5, PHP 7)
gmp_random — Random number
This function has been DEPRECATED as of PHP 7.2.0. Relying on this function is highly discouraged.
Description
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
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:
