note 103027 added to language.oop5.late-static-bindings

In my opinion late static binding is an anti pattern but there are some benefits though: <?php class MyClass extends ClassReference { } ?> MyClass::getQualifiedName() returns the full class name including namespace information. This prevents you from passing class names as plain strings and still lets you take advantage of code completion and type browsing. MyClass::cast() ensures the type of an object to be of a certain class. This is a kind of type hinting. <?php abstract class ClassReference { final public static function getQualifiedName() { return get_called_class(); } final public static function cast($object) { $className = get_called_class(); if (!is_object($var) || !($object instanceof $className)) { throw new \UnexpectedValueException("Cast failed. Argument is not of type " . $className . "."); } return $object; } } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 109.192.56.140 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.late-static-bindings.php Edit -- https://master.php.net/note/edit/103027 Del: integrated -- https://master.php.net/note/delete/103027/integrated Del: useless -- https://master.php.net/note/delete/103027/useless Del: bad code -- https://master.php.net/note/delete/103027/bad+code Del: spam -- https://master.php.net/note/delete/103027/spam Del: non-english -- https://master.php.net/note/delete/103027/non-english Del: in docs -- https://master.php.net/note/delete/103027/in+docs Del: other reasons-- https://master.php.net/note/delete/103027 Reject -- https://master.php.net/note/reject/103027 Search -- https://master.php.net/manage/user-notes.php
