note 124501 added to class.weakreference

You might consider to use WeakReference in your Container class. Don't forget to create the object into a variable and pass the variable to WeakReference::create() otherwise you going to ->get() null. Consider as wrong solution, which returns null <?php /** * @return App */ public static function app() : App { if (!static::$app) { static::$app = WeakReference::create(new App()); } return static::$app->get(); } ?> Consider as GOOD solution, which returns App instance <?php /** * @return App */ public static function app() : App { if (!static::$app) { $app = new App(); static::$app = WeakReference::create($app); } return static::$app->get(); } ?> ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.195 (proxied: 86.4.204.248) ---- Manual Page -- http://php.net/manual/en/class.weakreference.php Edit -- https://master.php.net/note/edit/124501 Del: integrated -- https://master.php.net/note/delete/124501/integrated Del: useless -- https://master.php.net/note/delete/124501/useless Del: bad code -- https://master.php.net/note/delete/124501/bad+code Del: spam -- https://master.php.net/note/delete/124501/spam Del: non-english -- https://master.php.net/note/delete/124501/non-english Del: in docs -- https://master.php.net/note/delete/124501/in+docs Del: other reasons-- https://master.php.net/note/delete/124501 Reject -- https://master.php.net/note/reject/124501 Search -- https://master.php.net/manage/user-notes.php
