function str_rand($len = 8, $class = 'a-zA-Z1-9')
{
static $init = 1;
if(1 == $init){
mt_srand((double) microtime() * 1000000);
$init = 0;

$chars = array();
for($i = 0; $i < $len; $i++){
$chars[] = chr(mt_rand(0,255));
}
return implode('', preg_grep('|['.preg_quote($class).']|',$chars));
}
Just a little bit different syntax for the second argument.
What's the big deal? :)
