<?php class C { protected $foo; private $bar; } $obj = unserialize("O:1:\"C\":2:{s:6:\"\0*\0foo\";i:42;s:6:\"\0*\0bar\";s:5:\"hello\";}"); var_dump($obj); var_export($obj->bar);

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).
