Password Checker

I was wondering if PHP can be leveraged for a password checker form. I was thinking it might be an idea to consider JavaScript too but I thought I would start here.

CHARACTER SET AVAILABLE CHARACTERS ENTROPY / CHAR
digits 10 (0-9) 3.32 bits
lower-case letters 26 (a-z) 4.7 bits
case sensitive letters and digits 62 (A-Z, a-z,0-9) 5.95 bits
all standard keyboard characters 94 6.55 bits

Sorry the table is messed up.

But given the various sets in use the entropy per symbol varies widely.

Perhaps a RegX might be the most expedient?

What are those decimal numbers? And what does "bits" mean? Try editing your post and wrapping the table with [text] [/ text] tags (the "Text" button) to retain the formatting.
