I will provide when you need “ex_starts/ch09_ex2” file:
1. Start the Chrome browser and run the application in the ex_starts/ch09_ex2 directory. This should display a page that allows you to enter three numbers and provides starting values for the three numbers.
2. Click on the Submit button. Note that this displays a message that includes the values of the three numbers but doesnt include the values for the rest of the message.
Write the code that processes the data entered by the user
3. Open the index.php file for this application and review the code. Note that it doesnt process the data. Instead, it just displays the data on the form.

thats formatted like this:
Number 1: 78
