Description:
------------
When utilizing the new DirectoryIterator of PHP5 (5.0.1) I get the following message.

Fatal error: Call to undefined method DirectoryIterator::fileExt() in C:\Apache2\htdocs\imagearchive\test.php on line 40

The function is listed in the documentation but only minimumly.

Reproduce code:
---------------
$sPath = 'C:\Apache2\htdocs'

foreach (new DirectoryIterator($sPath) as $oFile) {
  if ($oFile->isFile()) {
    echo 'isFile => '.$oFile->isFile().'<br />';
    echo 'getFilename => '.$oFile->getFilename().'<br />';
    echo 'fileType => '.$oFile->fileType().'<br />';
  }
}


Expected result:
----------------
isFile => 1
getFilename => apache_pb.gif
fileType => .gif (or something similar)

Actual result:
--------------
isFile => 1
getFilename => apache_pb.gif

Fatal error: Call to undefined method DirectoryIterator::fileType() in C:\Apache2\htdocs\imagearchive\test.php on line 40
