Simply write a PHP verification class and teach you how to write a good PHP program (including multiple verification rules)_PHP Tutorial

Many people often only use simple js verification when developing websites. When you accidentally write an extra comma or period in js, ie6 will not recognize it and skip the verification directly. In fact, the safest way is to verify the data entered by the user on the server side. I wrote a simple PHP verification class, which contains a variety of verification rules for your reference.
