run code in 300+ PHP versions simultaneously
<?php $var = ['someKey' => 'someValue']; echo $var['someKey']; $wasSet = isset($var['aKey']); if ($wasSet) { echo "was set"; } else { echo "was not set"; }

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).
