Note Submitter: phpnet at barrystaes dot nl ---- 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.
