run code in 300+ PHP versions simultaneously
<?php namespace ConstructorTest1 { class ConstructorTest1 { function ConstructorTest1() { echo "Constructor1 called."; } } } namespace { class ConstructorTest2 { function ConstructorTest2() { echo "Constructor2 called."; } } $test = new ConstructorTest1\ConstructorTest1(); $test = new ConstructorTest2(); }

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).
