"php regular expression for strong password validation [duplicate]" Answer’s

0

The best way to adapt that regex is to chuck it out and write some code instead. The required regex would be so long and complicated, you wouldn't be able to read it two hours after you wrote it. The equivalent PHP code will be tedious, but at least you'll be able understand what you wrote.

This isn't meant as a slam on you, by the way. Regexes are just barely suitable for password-strength validation in most cases, but your requirements are more complicated than usual, and it's just not worth it. Also, that regex you posted is crap. Never trust regexes you find floating around the web. Or any code, for that matter. Or, heck, anything. :-/
