Need help with eval function

I have some problems when I'm using eval();. Seems like it hates me or something... or I simply don't know how to use it.

I've being trying to use it and it doesn't do what I want... what it should hypothetically do...

Have you looked at the docs for it?

http://php.net/eval

While it's a complicated construct insofar as escaping content and whatnot, it's relatively straightforward as far as its functionality goes.

Really, though, it's not a good idea to use it for security purposes.

I have read that thing nearly ten times now...
