run code in 300+ PHP versions simultaneously
<?php $testing = 'foo'; $array = ['bar' => 'testing']; function test() { return 'testing'; } class Test { public function output() { echo 'called'; } } $string = 'test'; $test = new Test(); echo ${$array['bar']}; echo PHP_EOL; echo $$array['bar']; echo PHP_EOL; echo ${test()}; echo PHP_EOL; echo $test(); echo PHP_EOL; echo ($$string)->output();

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).
