But this is mostly intended for other features like generics/typed arrays for which I have read that speed is a big blocker. Anyway, if anyone is interested, I did some testing on parameter check. The code: --- class Customer {} function test(Customer $customer) {} $customer = new Customer(); $start = microtime(true); for ($i=1;$i<100000000;$i++) { // 100 million test($customer); } echo microtime(true) - $start; --- Tested 3 times, average time: 3.58s When I removed typehint from test() function, average time was: 2.76s Difference is 29.7% I know it is unrealistic scenario because there is nothing else in the code, I was just curios.
