note 49983 added to function.count-chars

Use: Great for checking for unique characters in a password. I wanted to check that my website users, when registering a user account, chose a "valid" (not-so-easily-guessed) password. One of the many checks was that the password must have 6 unique characters. I was tying myself in knots with all kinds of recursive array calling when I was offered this wonderful one line solution: function check_password($password) { #Have 6 unique characters if (count(count_chars($password, 1)) < 6) return false; # # other checks returning false as necessary # # return true; } I cannot claim this wonderful line for myself - a Mr Lynch suggested this to me.
