title: Unable to set upload_tmp_dir on IIS
body: <p>So I'm trying to set the <code>php upload_tmp_dir</code> setting on an IIS machine.</p>
  
  <p>I changed the setting in <code>php.ini</code> but <code>phpinfo()</code> still shows the default folder. I checked the permissions of <code>IIS_IUSRS</code> who have write, read, modify, etc.</p>
  
  <p>I also ran this to check if the new folder was writable:</p>
  
  <pre><code>$filename = 'C:\inetpub\temp\uploads';
  if (is_writable($filename)) {
      echo $filename . ' is writable';
  } else {
      echo $filename . ' is not writable';
  }
  </code></pre>
  
  <p>I changed the <code>max_file_uploads</code> value to test if the PHP config being loaded was the most up-to-date, and it was.</p>
  
  <p>What am I missing?</p>
