    I only allowed letters, numbers, *, %, $, #, &, -, _, in the password, so I used the following regular expressions
    But looks like it's not working. Any suggestions or can anybody give me a correct one?

    preg_match("/^[\w\*\$#&\%\-[0-9]]{6,15}$/", $password)
    will work, I think.

    \w shall be stand for [a-zA-Z0-9_], right? Then why add [0-9]? Do we need to add \ for %?

    From php.net
    
The special regular expression characters (that need to be escaped) are: . \ + * ? [ ^ ] $ ( ) { } = ! < > | : -
    Code (markup):
