Probably the best way is to simply read from /dev/urandom, but a plethora of examples can be found in this article (sorry for the non SO link):

There is also a php library if this is what you are looking for:

At http://php.net/manual/en/function.mt-rand.php, there is a warning that says, "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 openssl_random_pseudo_bytes() instead". See http://php.net/manual/en/function.openssl-random-pseudo-bytes.php.
