You can end a generator by return;ing. 2. An empty Generator from a function that doesn't even have code to yield anything doesn't make sense. Just return an empty iterator, like ArrayIterator([]). Previous Comments: ------------------------------------------------------------------------ [2021-02-12 08:43:35] petr dot vejchoda at seznam dot cz Description: ------------ I was looking for a way to end a end a generator prematurely without necessity to make it to the end of function/method. Also way of marking a function/method as an empty generator. And I found none. If there is one, one can say I can't google properly, or one could also say it was not written in the documentation. Test script: --------------- abstract class Base { __construct() { foreach($this->generator() as $key => $value) { $this->doSomething($key, $value); } } protected abstract function generator(): traversable; } class Child extends Base { // empty generator?? protected function generator() { if (false) { yield null; } } } Expected result: ---------------- I would appreciate some language construct like yield break; that would end the generator prematurely, or could be used to simplify empty generator syntax. yield from new EmptyIterator(); is not really an option for me, sorry, thats just plain ugly. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80735&edit=1
