Exercise 6 Develop an HTML web form page that has a set of checkboxes asking the user what fruit he/she likes the best. The fruits are apple, orange, banana, kiwi and melon. First make the form such that only one selection is possible, then modify the form to allow multiple selections. Include a Submit button in the form. Write two PHP scripts that process the submitted form and echo back to the user the favourite.fruit(s) that was/were selected Also include in the PHP script some code that checks if the user submitted an empty form - no checkboxes clicked. The code should display a warning for the user. Take a few screenshots to show that your program works correctly
