<?php class Param extends ArrayObject { public function offsetGet($name) { if (!$this->offsetExists($name)) return null; } } $data = new Param(array('foo' => 12)); var_dump($data['bar']);
Output for git.master, git.master_jit, rfc.property-hooks
Deprecated: Return type of Param::offsetGet($name) should either be compatible with ArrayObject::offsetGet(mixed $key): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /in/Bs8m4 on line 5 NULL
