I'm guessing you're worried about the distribution of mt_rand(). I have tested it and it is very level and both bounds are inclusive.

I added my test to the comments of the documentation for mt_rand() on the php manual, but it was removed by a silly moderator due to politics that are too long winded to go into here.
