note 114305 added to language.oop5.interfaces

Despite my expectations, it seems PHP does not support variables of type interface!? (using PHP 5.5) <?php interface InterfaceText { public function setText($text); } class Sticker implements InterfaceText { public function setText($text); } // While this is possible: $Cool = new Sticker (); // You can not make interface variables. $IntfCool = new InterfaceText($Cool); // ^ Fatal error: Cannot instantiate interface InterfaceText() // or cast them directly: $IntfCool = InterfaceText($Cool); // ^ Fatal error: Call to undefined function InterfaceText() ?> Being used to what other languages allow Interfaces, it seems PHP has no runtime support, i now see it a static class that generates parse-warnings to force implementation. ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/language.oop5.interfaces.php Edit -- https://master.php.net/note/edit/114305 Del: integrated -- https://master.php.net/note/delete/114305/integrated Del: useless -- https://master.php.net/note/delete/114305/useless Del: bad code -- https://master.php.net/note/delete/114305/bad+code Del: spam -- https://master.php.net/note/delete/114305/spam Del: non-english -- https://master.php.net/note/delete/114305/non-english Del: in docs -- https://master.php.net/note/delete/114305/in+docs Del: other reasons-- https://master.php.net/note/delete/114305 Reject -- https://master.php.net/note/reject/114305 Search -- https://master.php.net/manage/user-notes.php
