PHP Zend_Crypt_Math::rand Exemples

rand() public méthode

Will attempt to read from a systems RNG if it exists or else utilises a simple random character to maximum length process. Simplicity is a factor better left for development...

public rand ( string | integer $minimum, string | integer $maximum ) : string
$minimum	string | integer
$maximum	string | integer
Résultat	string
