PHP gmp_random() function

As of my last update in September 2021, PHP does not have a built-in gmp_random() function to generate random numbers using the GMP (GNU Multiple Precision) extension. The GMP extension primarily focuses on arbitrary precision arithmetic, providing functions to work with large integers accurately.

If you need to generate random numbers in PHP, you can use the rand() function or the more modern random_int() function, both of which are available in PHP’s core without the need for the GMP extension.

1. rand() function: The rand() function generates a random integer between the specified minimum and maximum values.

$randomNumber = rand($min, $max);

2. random_int() function: The random_int() function generates a cryptographically secure random integer between the specified minimum and maximum values.

$randomNumber = random_int($min, $max);

Please note that random_int() is considered more secure for cryptographic purposes, while rand() is suitable for general random number generation.

If you specifically require random numbers with arbitrary precision using the GMP extension, you can utilize GMP functions to manipulate the output of the rand() or random_int() functions, but this may not be the most efficient approach. For most use cases, the core PHP random number functions should be sufficient and easier to work with.
