One way to create interactive web pages is to ask for user input. The way to get the information from a user is through a web form. once the user submits the information, it then process (by PHP) and depending on what process you have programmed, it displays the results.
In my example, i will be asking for a user's name, once the user submits their name, i will display a friendly rely with their name.
for example, the page will ask for the user to enter their name, and when they submit the form, the form will be process and depending on what the user submits, it will give a message like: Hi username! PHP is great!
So here is the code to make it happen:
1. copy and paste the following code into your editor, you can use notepad i f you don't have a web editor:
Code:
