<?php class A implements \IteratorAggregate { private $a = 'a'; private $b = 'b'; public function getIterator() { return new \ArrayIterator($this); } } $a = new A(); foreach ($a as $key => $value) { var_dump(array($key, $value)); }
Output for git.master, git.master_jit, rfc.property-hooks
Deprecated: Return type of A::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /in/nZGIb on line 8
