title: How do I configure ctags to index PHP namespaces and their aliases?
body: <p>when using PHP namespaces the code I work on uses a large number of namespace aliases, e.g.</p>
  
  <pre><code>&lt;?php
  namespace foo;
  
  use bar\baz\qux as bazQux;
  
  ...
  
  $a = new bazQux();
  </code></pre>
  
  <p>Is it possible to configure Exuberant Ctags to index the use of these namespace aliases so that I can jump from a line where the alias is used (the instantiation above) straight to the real class? If that's not possible, what's the best compromise that can be achieved?</p>
  
  <p>I've seen somewhere a not-yet-integrated patch for ctags to use a PHP tokenizer for PHP support instead of the current regex-based implementation; I'd like to continue to use a stock ctags if possible though, rather than having to patch and compile a version myself.</p>
