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?
