PHP Simple Form

This page provides a very simple PHP form example. The code shows how to make a self referencing form in PHP. A test is performed at the top of the script. If the HTTP request was a get the value gets set to "1" or true, otherwise $isGet is set to an empty value. The variable can then be used to see whether to process a get or a post.
