run code in 300+ PHP versions simultaneously
<?php class Bar { } class Foo extends Bar {} $a = "Foo"; $b = "Bar"; function foo() { return 'Foo'; } var_dump(foo() instanceof $b);

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).
