After one particularly frustrating day [looking at how the Zend engine works] I asked a colleague (Andy Wharmby) about the issue I was looking at. Then a miracle happened - he'd not only looked at it but had documented it (and many other things) in a set of charts.

She has linked to the charts (Open Office format) for the results of some tests her friend had already run. They're a bit out of date and some parts might be inaccurate, but they're still a good start.

PHP DocWriter is a set of PHP classes that allows you to create documents in OpenOffice.org XML format (that is, StarOffice/OpenOffice.org documents). You can download the library files from here (http://phpdocwriter.sourceforge.net/download.php?lang=en). Also, you can find installation steps in the mentioned link.

With the library installed, it's a simple matter of creating a new object, defining properties and using methods on it and exporting it from the script. There are several examples included in the tutorial, everything from a simple "Hello World" example out to creating documents with meta-information and tables.
