title: Vim PHP omni completion
body: <p>I'm trying to get PHP autocompletion right in Vim. Right now when I do a <code>$blog = new Blog(); $blog-&gt;</code> and then hit <code>CTRL+X CTRL+O</code> I'd expect omnicompletion to return all the functions in the class <code>Blog</code>. </p>
  
  <p>Instead, it returns all functions for the entire project. I've built ctags for my project like so: <code>ctags -R *</code></p>
  
  <p>Is there any way to make the autocompletion context-aware?</p>
