run code in 300+ PHP versions simultaneously
<?php $tests = array( html_entity_decode('&#xd800;&#xdc00;', ENT_NOQUOTES, 'utf-8'), html_entity_decode('&#x1D11E;') ); foreach ($tests as $s) { var_dump($s); var_dump(json_encode($s)); var_dump(json_encode($s, JSON_UNESCAPED_UNICODE)); }

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).
