With the _ callstatic magic method of PHP 5.3, you can perform the magic by class name and method name at the same time.

It's hard to explain what you want to do. In short, with _ callstatic, you can save a lot.Code. In addition, this method can be called in the subclass. In combination with get_called_class, The subclass also performs magic.

Previously, when using the. NET Component Castle's activerecord,. Net version 2.0 can add a static getbyid method to each subclass. Now, PHP can also do this..

 

<? Phpclass activerecordbase {/** as of PHP 5.3.0 */public static function _ callstatic ($ name, $ arguments) {if ($ name = 'getbyid ') {$ id = $ arguments [0]; return get_called_class (). '('. $ id. ')';} Throw new exception ('invalid method :'. $ name) ;}} class person extends activerecordbase {}// output: Person (123) echo person: getbyid (123);?>
