What do you mean by find other sites hosted on a server? How do you want to find other sites? What do you want to do with those found sites?

What form you are going to use? And what do you mean by how to get the data? Do you mean how the data posted from a form get from PHP?

I am not quite getting what you are tying to ask and do :slight_smile:
