Syntax hinting in Vim

Question

I've been using Vim for quite a while now, and while the code-completion (omni, dictionary, etc) works fine I've been missing one thing.

Syntax-hinting, so basically I'd like to know what arguments a function accepts, rather than look it up online I'd like to have it somewhere in Vim, preferably in a box above the current line or something.

Is there any way to achieve this, I mostly work with PHP, Python and C++ so I need it for those languages.

Edit: I do already have ctags installed, but from what I could tell it didn't provide syntax-hinting, tried it with PHP standard functions, dunno if I've overlooked something.

There's also the option of using snipMate and entering all standard library functions, but that's a lot of work, would've imagined that someone already did that (And yes there's something like ultiSnips that does but it's inferior to snipMate)
