Textmate autocompletion and class outline for PHP project

I'm using PDT, but want to switch to any lightweit editor. First I want to try Textmate. Eclipse has several useful features:

• class outlile to get list of properties and methods (with signature) to navigate;
• type hierarchy, it is like class outlile but it shows full inheritance tree;
• autocompletion for custom classes names, methods etc. (not only for standard functions);
• go to declaration feature

Does Textmate provide this features, or is there bundles to get such functional?

I know it can be frightening — it was for me — but you can code very efficiently with Vim. It's definetly not a turnkey solution but if you have some time between projects it's worth it.

• Taglist and tagbar are plugins that provide code navigation.
• There are a number of solutions for autocompletion.
• you can go to declaration with gd in a single file or with exuberant ctags and ctrl-] in more complex situations.
