run code in 300+ PHP versions simultaneously
<?php $val = []; for($i=0; $i<30;$i++) { $val[] = mt_rand(); } echo strlen(json_encode($val)); echo "\n"; echo strlen(gzcompress(json_encode($val))); echo "\n"; echo strlen(base64_encode(gzcompress(json_encode($val)))); echo gzcompress(json_encode($val));

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).
