If you need quickly grab some data from Lotus Notes database then create in notes View with data you want to export and open this view via url:
this will give you a nicely formated XML :)
Hope this helps!
Given the fact that this extension uses Notes' C API interface, you're stuck with Windows. If you're going to go that route, you can use Notes' COM interface just as easily. You won't have to use this extension, and you'll get a much richer functionality.
However, if you would rather stay cross-platform, a fully supported technique is to use XML. You access Domino via file_get_contents or fopen (or similar method), and Domino returns XML, which you then parse within PHP. It is cross-platform, requires no extensions, and is the recommended solution.
Introduction to these techniques (including using the above extension) is covered here. Restore this back into a single line (broken because of wordwrap): http://www-128.ibm.com/developerworks/lotus/
This is an unmaintained Windows-only extension.
You will need Visual C++ 6.0 to build it; use the CVS Web link below to obtain the source.
