I've just implemented the SharePointAPI for PHP which can be found https://github.com/thybag/PHP-SharePoint-Lists-API
I was able to retrieve all of the SharePoint Lists from the WSDL, and was able to use the ->read($list) function to retrieve a List which holds Document folders and files.
Within the list, if the item is a file, I'm able to download it fine.
However, if the item is another folder (a subdirectory), how do I access that directory's folders and files?
The ->read($list) function doesn't work, and I'm kind of at a loss. Does anybody know how I can read a List item's folders and files as it were a List?
Although part of me suspects you are probably the person who ended up managing to answer their own question over on the github issues; I thought I may as well repost that answer here in case others have the same problem.
Essentially (although its a bit of a work around) you can get a listing of the contents of a folder in a sharepoint list, by calling the following method:
$sp->read($listName, NULL,//$limit NULL,//$query NULL,//$view NULL,//$sort "<Folder>" . $listName . "\\" . $folderName . "</Folder>"//$options )
Hopefully once manage to find a bit of spare time, I'll add a dedciated method for doing this to the library, just to make it a little more straight forward in future.
