run code in 300+ PHP versions simultaneously
<?php class a { public $b = 'foo'; } $first = new a(); $second = clone $first; $second->b = 'baz'; var_dump( $first ); var_dump( $second );

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).
