I really appreciate your help but I am still a little unclear on exactly what to do. I understand the mapscript for a WCS request, but I am still unsure how to download the data once it is returned from the server. You gave an example of a WCS GetCoverage Request as:
$mapurl .= "request=GetCoverage&coverage=[layer_name]&crs=epsg:28992&resx=25&resy=25&format=image/tiff” So I am assuming that there is some php call that can be used to capture the returned image but I am not sure how to do this. Sorry to ask so many questions but there is just no good documentation out there for WCS.
