<?php class Foo implements IteratorAggregate { public function getIterator() { return new ArrayIterator([]); }} function foo(iterable $bar) { var_dump($bar); } foo(new Foo());
Output for git.master, git.master_jit, rfc.property-hooks
Deprecated: Return type of Foo::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /in/ios53 on line 3 object(Foo)#1 (0) { }
