i uses array_rand to handle the random,thx Scrow for the new idea

[scrowler]

yeah, there are various ways of doing it... i'll explain what a couple of the functions do:

glob() - retrieves a list of all files in a directory by the supplied flags (* is everything) and returns them in an array

mt_srand() - seeds the better random number generator

mt_rand() - generates a number using the better random number generator [better version of rand()]

count() - returns the number of keys in an array, we use it in this instance to find the maximum array key so we can choose a random one. also see sizeof()
