mt_rand
mt_rand — Generate a random value via the Mersenne Twister Random Number Generator.Description
mt_rand(
): int
Description
mt_rand( int $min,
int $max ): int
Caution: This function does not generate cryptographically secure values, and should not be used for cryptographic purposes. If you need a cryptographically secure value, consider using random_int(), random_bytes(), or openssl_random_pseudo_bytes() instead.
Many random number generators of older libcs have dubious or unknown characteristics and are slow. The mt_rand() function is a drop-in replacement for the older rand(). It uses a random number generator with known characteristics using the » Mersenne Twister, which will produce random numbers four times faster than what the average libc rand() provides.If called without the optional min, max arguments mt_rand() returns a pseudo-random value between 0 and mt_getrandmax(). If you want a random number between 5 and 15 (inclusive), for example, use mt_rand(5, 15).
Parameters
min
Optional lowest value to be returned (default: 0).
max
Optional highest value to be returned (default: mt_getrandmax()).
Return Values
A random integer value between min (or 0) and max (or mt_getrandmax(), inclusive), or false if max is less than min.More information about mt_rand on official PHP documentation site
