gmp_randomRandom number 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 gmp_random(int
$limiter = 20)
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 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. Caution
This function does not generate cryptographically secure values, and must not be used for cryptographic purposes, or purposes that require returned values to be unguessable. If cryptographically secure randomness is required, the Random\Randomizer may be used with the Random\Engine\Secure engine. For simple use cases, the random_int and random_bytes functions provide a convenient and secure API that is backed by the operating system’s CSPRNG. Parameters
Return ValuesA random GMP number. Examples
