Generate a Unambiguous Random Password

Published in: PHP 

This function generates a random password of a specified length in lower or mixed case letters and numbers. Ambiguous characters, such as I, L, 1, 0, and O, are left out so the user can easily read the password.

  2. {
  3. 	$a = "abcdefghjkmnpqrstuvwxyzABCDEFGHJKMNPQRSTUVWXYZ23456789";
  4. 	if(!$mixed_case) $a = strtolower($a)
