<?php class Foo { protected $bar; private $foo; } $foo = new Foo(); var_dump((array) $foo); var_dump( $foo->{"\0*\0bar"}, $foo->{"\0Foo\0foo"} ); $foo->{"\0*\0bar"} = 'baz'; $foo->{"\0Foo\0foo"} = 'bar'; var_dump(array($foo));

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).
