title: Why do I get "permission denied" in PHP when trying to rename a directory?
body: <p>I chmod'ed the directory to 777, same with the directory contents. Still, I get a "permission denied" error. Does PHP throw this error if apache is not the group/owner, regardless of the file permissions? Here's the call that's failing:</p>
  
  <pre><code>rename('/correct/path/to/dir/1', '/correct/path/to/dir/2');
  </code></pre>
