Regx For Password Complexity

[biglurch]

Im trying to write a password complexity regular expression for php this is what i got so far i want it to require 6-12 chars 1 cap letter 1 number and allow symbols and small case letters. Any suggestions please let me know.

/(^[A-Za-z0-9]{1,}$){6,12}/

Live by the code, Die by the code!!

i'm not sure whether it's all possible in one expression. i'd love to see a solution!

how about this?

function validPassword($pwd){
 //taken from [URL unfurl="true"]http://www.breakingpar.com/bkp/home.nsf/0/87256B280015193F87256C4F005D3717[/URL]
   $pattern = '/^\w*(?=\w*\d)(?=\w*[a-z])(?=\w*[A-Z])\w*$/';
   if (strlen($pwd) < 6) return false;
   if (!preg_match($pattern, $pwd)) return false;
   return true;
}

You need to fine tune the syntax, but it can be on the same line

if ( strlen($pwd) >= 6 && strlen($pwd) <= 12 && $pwd =~ /[A-Z]/ && $pwd =~ /\d/ && $pwd !~ /[^A-Za-z0-9_]/ )
