run code in 300+ PHP versions simultaneously
<?php $me = __FILE__; $xml = <<<ENDOFXML <!DOCTYPE root [ <!ENTITY foo SYSTEM "$me"> ]> <foo>&foo;</foo> ENDOFXML; echo "libxml version: " . LIBXML_DOTTED_VERSION . "\n\n"; $s = simplexml_load_string($xml, null, LIBXML_NOENT); var_dump($s); echo "\n"; var_dump(base64_decode($s));

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).
