<?php $arr = [1, 2, 4]; $obj = (object)$arr; var_dump($obj); var_dump($obj->{1}, $obj->{2}, $obj->{3}); var_dump($obj->{'1'}, $obj->{'2'}, $obj->{'3'}); ?>

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
