Using PHP: A painting company has determined that for every 115 square feet of wall space, one gallon of paint and eight hours of labor will be required. The company charges $20.00 per hour for labor. Write a web app in PHP that asks the user to enter the square feet of wall space to
be painted and the price of the paint per gallon in a HTML form. The program should display the following data:
• The number of gallons of paint required
• The hours of labor required
• The cost of the paint
• The labor charges
• The total cost of the paint job
