Question: Tip, Tax, and Total: Design your own HTML form and corresponding PHP page to calculate the total amount of a meal purchased as a restaurant.
The form should simply ask the user to enter the charge for the meal, pass the value to your PHP using either GET or POST , and then calculate the amount of a 15 percent tip and a 7 percent sales tax.
The PHP should display the cost of the meal, the tip, the sales tax, and the total.
You need to make well-formed and clean code. You should not copy and paste the code from other source.
