I have a website that will collect sensitive data, and I want to write that data to a mysql database on my server. I need a php script that will process the form securely.

Until recently I have used either Phorm or FormTools for processing. I can't use FormTools because the data appears in the url line. Not sure about Phorm. But before buying in an expensive outsourced service, I wanted to tap the collective wisdom of webmaster-talk.
