random login code algorithm

[Anon]

Hello,

I am trying to code an algoritm to get PHP to randomly create a 50-character long string of leters a-z and numbers 0-9.

Does anyone know how I can achieve this?
I imagine I should need to use a for-loop, which cycles 50 times and randomly generates an apropriate character each time, but how can I get it to generate a random character of a-z,0-9?

Thanks, James.

Well you could put all of the characters into an array a-z A-Z and 0-9 then generate a random number for each character in your password that is between 0-61.
