Password validation check

I would like to check a user's password as they enter it to make sure it has Capital letters, numbers and a special characters. I have the code to pass  and check the information as it is being entered. but is there a easy way to find out if at least one on the characters being passed in the form filed is a Capital letter, number and a special character?

Now you just changed my thought process, is there a way to tell them if there password is Week, Good or Strong as they type their password using this code. Should I ask this in a new question on Expert-exchange?
(no points...)

If you do use a big combined regex, be sure to understand it.  I'm not so hot with regex's so I usually use smaller ones so I know they work they way they want.

I think the "weak,strong,.." question should be a new thread. But I think the answer depends on your criteria. Anyway you might want to check cflib.org and see what it has to offer in the area of password functions, like

Good luck!
yeah, open a new question related to this question regarding checking weak, strong, we can guide u

I did open a new question, can you please check for it "Check for password strength as the person creates it"

Thank you

In the mean time, I'm going to play with this current post..
