title: PHP is_readable fails but opendir works
body: <p>Basically what it says on the tin:</p>
  
  <pre><code>if(is_dir($dir))
      echo $dir . " is a directory\n";
  
  if(is_readable($dir))
      echo $dir . " is readable\n";
  
  if($this-&gt;handle = opendir($dir))
      echo $dir . " opened\n";
  </code></pre>
  
  <p>Returns:</p>
  
  <p>\\HTPC\MOVIES is a directory</p>
  
  <p>\\HTPC\MOVIES opened</p>
  
  <p>Which is wierd? I can iterate through the files in the directory but apparently it is not readable. It doesn't really matter as like I said I can still read the files, however  I just find it a little odd.</p>
  
  <p>Does anyone have any thoughts?</p>
