Description:
------------
The method getChildren of DirectoryIterator does not exists in PHP 5.2.3 and PHP 5.2.4 dev but the PHP Manual does not say anything about it.

Reproduce code:
---------------
dataDir           = './data';
$directoryIterator = new DirectoryIterator($dataDir);

foreach ($directoryIterator as $idDir)
{
	if ($directoryIterator->isDot())
	{
		continue;
	}

	if ($directoryIterator->isDir())
	{
		$companyId           = $idDir->getFileName();

		// Report directory iterator
		$subDirIterator      = $idDir->getChildren(); //bug
        }
}



Expected result:
----------------
DirectoryIterator::getChildren() should return a RecursiveDirectoryIterator as stated in the PHP Manual

Actual result:
--------------
Fatal error: Call to undefined method DirectoryIterator::getChildren() in D:\wvbsrc\newswire\Edinet\test.php on line 18
