security assist and data assist should not have an issue on a php server running safe made, but I believe you will have an issue with HTML Editor.
You will also run into a problem with file uplaod if you are resizing the image, as well as framework builder.
I'm not 100% sure with html editor or file upload, so feel free to give them a try and see if it works. it should only be a 5 minute experiment to create a couple of test pages.
