Figured out what it was. There was an error in the php wrapper file in the campaignscollection class.
these two lines need to be modified in the createCampaignStruct function
$campaign['vawp_link_text'] = ($parsedReturn->content->Campaign->ViewAsWebPageLinkText);
$campaign['vawp_text'] = ($parsedReturn->content->Campaign->ViewAsWebPageText);
to
$campaign['vawp_link_text'] = ($parsedReturn->content->Campaign->ViewAsWebpageLinkText);
$campaign['vawp_text'] = ($parsedReturn->content->Campaign->ViewAsWebpageText);
(the capital P in WebPage is incorrect).
I also wrote another function that crates the xml as a raw string rather than using the simple xml library which simply will not let you encode html into it if anybody wants it.
