I am trying to setup a php testing server in Dreamweaver that connects to my webhost at webhostingpad.com. My webhost has php installed on it so I know I don't need to download xampp but I am still clueless as to how to set this up. Please help.

All you really need to do is FTP your PHP files to your hosting provider when you are ready to publish to the web.

You will need to create a site under SITE> New Site.

Then under this you will "Servers" set your connection to FTP, put in your login details on how you access the domain, switch over to Advanced, set the type of server (PHP/MySQL).

Once saved make sure the tick box is set to "remote"

Although for testing purposes, i tend use XAMPP for local dev
