There is such a cool thing - openserver. Set and test all what you want. It is unlikely that someone will execute php scripts on the server as a service. Because:
- it's not safe
- no one needs

I remember one site, there is a list of prepared questions, and the answer should be a CODE on one of the languages offered.
Write the code, and inside the asserts.

But I lost the link to this site, and Google can not find.
I also remember that he was not alone.
