My day job is no longer to write code, but I have a couple of projects I work on at night, so take my opinion for what it's worth. I have one project that's mostly static content and a couple of calculator forms. On submit, I an ajax call to post to a PHP script, it returns a json object with some data, and I display it. When I see PHP getting ripped, I always wonder, what am I supposed to use if not this? I know this is relatively simple, but my choices were to do the calculations in javascript or let PHP handle it - and PHP seemed to me as the right choice because I eventually may want to capture some of the input data, send it to a db, etc.
