saving a document in the word 2003 format

http://phpword.codeplex.com/documentation includes an example of how to save in the Word 2007 docx format:

$objWriter = PHPWord_IOFactory::createWriter($PHPWord, 'Word2007');
$objWriter->save('helloWorld.docx');

Is it possible to save a document in the Word 2003 format instead? If not are there other libraries that might?

The project has been transfered to Github : https://github.com/PHPOffice/PHPWord/. Actually, reading a file Word 97-2003 is in the pipe. So we will implement Word97 writing feature, after that.

Else :

• You can write RTF/DOCX Files with PHPWord read by Word97 (with Addin for DOCX)
• You can write RTF Files with PHPRtfLite read by Word97
• You can write Word97 with the PHP extension COM : Sample (only for Windows and if you have installed Office)
