run code in 300+ PHP versions simultaneously
<?php namespace A { /** * My magic test class * * @return \DateTime */ function getdate() { return 'what_ever'; } \getdate(); // ctrl + click on getdate, should go to date.php stubs. Hover is also invalid. This looks like a problem with selection engine } namespace B { print_r(getdate()); // shouldn't work as \DateTime. \getdate() fallback ;; // fix CA ;) }

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).
