gmp_random — Random number
This function has been DEPRECATED as of PHP 7.2.0. 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:
