The shortcomings it tries to fix is the speed of the execution of the language, something PHP already gets better than other dynamically typed languages such as ruby. There's lots of good reasons to pick PHP as the language to develop A web application on and with HHVM in the mix the reasons will be greater still. PHP is a real programming language, if your greatest knock against it is the inconsistent order of function parameters then I don't really think you do have a knock against it unless of course you want to take the same swipe against C.
