run code in 300+ PHP versions simultaneously
<?php function mytest(){ return 1==1; if (1==1) { # code... return '测试'; } echo '测试' } function test2(){ mytest(); return 'test'; return 'test888'; } // echo mytest(); echo test2();

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).
