Can anyone help ?

Answer 1

Firstly, you can just get a random number between 10+26+26=62 6 times, and then calculate the resulted string, this seems easy enough.

<?php
function ()
{
$letters={a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,0,1,2,3,4,5,6,7,8,9,10}
return array_rand($letters).array_rand($letters)......... // you get the point

?>
