note 87373 added to function.rand

I've noticed alot of people doing long winded random string generators so I thought I'd post my one liner to give a bit of a fresh approach. The concept is simple. The rand() function generates a number made up of 10 different digits. (0,1,2,3,4,5,6,7,8,9). To generate an equivalent string I only need 10 alpha characters to replace the numbers. I am using (p,q,r,s,t,u,v,w,x,y). I chose these letters because they don't include any characters that resemble numbers and was the best set generated by the chr() function. Anyway, to create a 6 character random string I do this: $rand = preg_replace("/([0-9])/e","chr((\\1+112))",rand(100000,999999)); The length of the string is based on the length of the random number generated. This would also mean you could generate a random string at a random length too if you wanted.
