note 96137 added to language.oop5.interfaces

Interfaces can define static methods, but note that this won't make sense as you'll be using the class name and not polymorphism. ...Unless you have PHP 5.3 which supports late static binding: <?php interface IDoSomething { public static function doSomething(); } class One implements IDoSomething { public static function doSomething() { echo "One is doing something\n"; } } class Two extends One { public static function doSomething() { echo "Two is doing something\n"; } } function example(IDoSomething $doer) { $doer::doSomething(); // "unexpected ::" in PHP 5.2 } example(new One()); // One is doing something example(new Two()); // Two is doing something ?> If you have PHP 5.2 you can still declare static methods in interfaces. While you won't be able to call them via LSB, the "implements IDoSomething" can serve as a hint/reminder to other developers by saying "this class has a ::doSomething() method". Besides, you'll be upgrading to 5.3 soon, right? Right? (Heh. I just realized: "I do something". Unintentional, I swear!) ---- Server IP: 64.71.164.2 Probable Submitter: 69.166.47.131 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.interfaces.php Edit -- https://master.php.net/note/edit/96137 Del: integrated -- https://master.php.net/note/delete/96137/integrated Del: useless -- https://master.php.net/note/delete/96137/useless Del: bad code -- https://master.php.net/note/delete/96137/bad+code Del: spam -- https://master.php.net/note/delete/96137/spam Del: non-english -- https://master.php.net/note/delete/96137/non-english Del: in docs -- https://master.php.net/note/delete/96137/in+docs Del: other reasons-- https://master.php.net/note/delete/96137 Reject -- https://master.php.net/note/reject/96137 Search -- https://master.php.net/manage/user-notes.php
