I'm no statistician, but something tells me that the odds of getting 1 PMC are a little over 5%. Seems the basic random function in PHP isn't quite up to the task. Might have to increase the order of magnitude.
Oh well, some lucky miners right now at least.
I don't know if that is your case, but I already had some weird things with php rand. Alternnatively you may go for /dev/urandom
I think you may also use mt_rand but I think it is just faster but based on the same state as in rand
/dev/urandom http://codeascraft.com/2012/07/19/better-random-numbers-in-php-using-devurandom/
