Php scalable verification instances (which can be verified by email, mobile phone number, URL, and so on)

This article mainly introduces php scalable verification. The example analyzes php's common verification techniques for emails, mobile phone numbers, URLs, and so on, which are very useful. For more information, see

This article describes the php extension verification classes. Share it with you for your reference. The specific analysis is as follows:

An extensible php verification class is introduced here,
You can adjust the implementation of various types of verification in the class. Now it is the basic implementation method.
To add a rule, define the method directly. The method name is the rule name. For details, refer to usage.

Require_once ('. /Validator. class. php '); $ data = array ('nickname' => 'heno', 'realname' => 'steven', 'age' => 25, 'mobile' => '000000'); $ validator = new Validator ($ data); $ validator-> setRule ('nickname', 'required '); $ validator-> setRule ('realname', array ('length' => array (1, 6), 'required'); $ validator-> setRule ('age ', array ('requestred', 'digit'); $ validator-> setRule ('mobile', array ('mobile ')); $ result = $ validator-> validate (); var_dump ($ result); var_dump ($ validator-> getResultInfo ());

The Validator. class. php file is as follows:
