rand() function

$RandomValue = rand($MinValue, $MaxValue);

rand does not generate cryptographically secure values, and should not be used for cryptographic purposes.

Min and max are inclusive.

mt_rand() used to be used in place of ran() because it was faster, but from PHP7.1 rand uses same as mt_rand.

Cryptographically secure random number generators

random_int()

random_bytes()

openssl_random_pseudo_bytes()
