I'm always happy to help a fellow (confused) programmer. ;)

The idea of variable functions and using a variable as a function name 
is kind of weird, but can also allow you to do some cool tricks.

Personally I like to check with is_callable before I use a variable 
function name, just to make sure the function actually does exist, but 
other than that I don't know of any gotchas with this technique.
