Ask HN: Place to get code checked and get advice on it?

hey, recently I've had to start picking up PHP for university. As we do IT-security as a different subject I coded the first assignment for that class in PHP, to get to know PHP better and to try to fix the problem before I implement it in C++.

Now, I am not sure if this code and algorithm are as good as it could be (I am actually pretty sure it isn't) and I want to improve and learn. Hence I was wondering if there is a good place where people give advice on such.

Searching google I didn't seem to find anything matching with the terms I searched for and the forums I found usually had small snippets that were designed for other people to use.

Thanks in advance.
