run code in 300+ PHP versions simultaneously
<?php //namespace A\B; $a = [['x'], ['y'], ['z1'], 1, 2, 3, 4, 5, 'some text']; $time = microtime(true); for ($i=0; $i<1000000; $i++) { \count($a); } echo (microtime(true) - $time) . "\n"; $time = microtime(true); for ($i=0; $i<1000000; $i++) { count($a); } echo (microtime(true) - $time) . "\n";

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).
