Here’s a very useful function to generate a random string in php. I use this function quite often especially while working in core php projects.
function create_random_string($length=9) {
$salt = "abTUcdeIMNfjkl2m345noRqJKLr0s7tuvw1xyzABCD68EFGHpOPQSVWghiXYZ9".time();
srand((double)microtime()*1000000);
$res='';
$i=0;
while( $i <= $length )
{
$num = rand()%33 ;
$new = substr($salt,$num,1);
$res = $res.$new;
$i++;
}
return $res;
}
