note 106289 added to language.oop5.late-static-bindings

A tricky behaviour of LSB: If you forget a "static" keywork in the method definition you can get very unexpected results. <?php class BaseClass { public function callTest() { // static accidentally omitted static::test(); } protected static function test() { echo 'BaseClass::test<br />'; } } class ExtendedClass extends BaseClass { protected static function test() { echo 'ExtendedClass::test<br />'; } } class UserClass { public function useExtendedClass() { ExtendedClass::callTest(); // Static call of the *acidentally* non static method } public function test() { echo 'UserClass::test<br />'; } } BaseClass::callTest(); // BaseClass::test, as expected ExtendedClass::callTest(); // ExtendedClass::test, as expected $userClass = new UserClass(); $userClass->useExtendedClass(); // ExtendedClass::test is expected, but displays UserClass::test!!! ?> ---- Server IP: 69.147.83.197 Probable Submitter: 82.226.203.156 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.late-static-bindings.php Edit -- https://master.php.net/note/edit/106289 Del: integrated -- https://master.php.net/note/delete/106289/integrated Del: useless -- https://master.php.net/note/delete/106289/useless Del: bad code -- https://master.php.net/note/delete/106289/bad+code Del: spam -- https://master.php.net/note/delete/106289/spam Del: non-english -- https://master.php.net/note/delete/106289/non-english Del: in docs -- https://master.php.net/note/delete/106289/in+docs Del: other reasons-- https://master.php.net/note/delete/106289 Reject -- https://master.php.net/note/reject/106289 Search -- https://master.php.net/manage/user-notes.php
