PEAR Site Has OpenDocument Project For PHP
OpenDocument is a package to read, create or modify office documents in open document format.OpenDocument format is a replacement for proprietary office formats such as .doc or .xls. This package is a very useful tool for php developers and another point to switch from proprietary office formats to OpenDocument one, that means switching to open source software and standards.OpenDocument was developed as a project of Google Summer of Code 2006 Program.Package provides object oriented style for working with open documents, a little similar to DOM as for XML.
This is the description of a project on the PHP PEAR site. I have to say that it looks abandoned, but that could be a false impression. Here's hoping that work continues on this. This could give every PHP developer the potential to import or export ODF documents within his project.
