ACTIVITY

Write the above block of code into Notepad++ and save as action.php into your web folder

For your browser to parse the form it has to be opened by typing a url similar to http://localhost/form.html
When you hit the submit button your browser will parse the information you have entered into the form and display the message in the action.php file.
