gmp_randomRandom number

Warning

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.
