But this is only half of the story. In order for the information on the form to actually do something, it has to call some type of computer program into action. This program acts the information contained in the form. Here is a representation of the program that was used to run the last example. Echo is a php command that tells the server to display anything in the parenthesis on your browser screen.
Normal text is put inside quotes.
The periods are separators. In this case, it is the same variable that was in your form, name. The beauty of PHP is that you embed it into normal HTML pages. You give the file a name that ends in .php or .php3 . If the web server has PHP support installed, it knows that any file containing the ending .php or .php3 will have PHP script embedded inside of it.
