It should be: <?php $arr = [1, 2, 4]; $obj = (object)$arr; var_dump($obj); var_dump($obj->{0}, $obj->{1}, $obj->{2}); var_dump($obj->{'0'}, $obj->{'1'}, $obj->{'2'}); ?> Previous Comments: ------------------------------------------------------------------------ [2015-12-23 23:52:02] ajf@php.net This has been broken since at least PHP 5.4. ------------------------------------------------------------------------ [2015-12-23 23:50:41] ajf@php.net Description: ------------ If an array is casted to an object, its integer keys become inaccessible integer(!) key properties.
