note 119153 added to language.oop5.anonymous

Despite being anonymous, anonymous classes are named. get_declared_classes() will return anonymous classes (PHP 7.0.5). Because they are named, an anonymous class can also be aliased (not that its useful): <?php $a = new class { public $test = 123; }; class_alias(get_class($a), "Test"); $b = new Test; echo $b->test; // outputs 123 ?> Unlike anonymous functions, returning an anonymous class from a function will be a new instance of the SAME anonymous class each time. <?php function anonymous_function () { return function () { static $shared = 0; echo ++$shared; }; }; function anonymous_class() { return new class { static $shared = 0; public function __construct() { echo ++self::$shared; } }; } anonymous_function(); // outputs 1 anonymous_function(); // outputs 1 anonymous_class(); // outputs 1 anonymous_class(); // outputs 2 get_class(anonymous_class()) === get_class(anonymous_class()); // TRUE ?> ---- Server IP: 72.52.91.14 Probable Submitter: 2601:281:c401:1cc1:10dd:a922:6a95:d2cb ---- Manual Page -- http://php.net/manual/en/language.oop5.anonymous.php Edit -- https://master.php.net/note/edit/119153 Del: integrated -- https://master.php.net/note/delete/119153/integrated Del: useless -- https://master.php.net/note/delete/119153/useless Del: bad code -- https://master.php.net/note/delete/119153/bad+code Del: spam -- https://master.php.net/note/delete/119153/spam Del: non-english -- https://master.php.net/note/delete/119153/non-english Del: in docs -- https://master.php.net/note/delete/119153/in+docs Del: other reasons-- https://master.php.net/note/delete/119153 Reject -- https://master.php.net/note/reject/119153 Search -- https://master.php.net/manage/user-notes.php
