Random string generator PHP -

-

this question has answer here:

i'm trying create random string numbers , letters , found function , thought good, don't know if correct way create true random string or if there easier way this? below have:

function randomgen() {     $chars = '0123456789abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz';     $length = strlen($chars);     $random;      ($i = 0; $i < 8; $i++) {         $random = $chars[rand(0, $length - 1)];     }      return $random; }

you try using $random = substr(str_shuffle(md5(microtime())), 0, 8);, output same amount of random characters have in example. prefer method on doesn't require put in expected characters , more importantly, can done in 1 line of code!
