Make a simple PHP web app that contains a "to-do" list. You should be able to add, mark as complete, edit, and delete items from the list. This page could be as simple as having a textbox with an add button next to it. Clicking the add button should make the item appear at the bottom of the page with a checkbox next to it, an edit button, and a delete button. If the checkbox is checked, it should remain checked if more items are added. Clicking the edit buttor will allow the current task to be edited, and when complete, it should display "edited" and not the original task. Clicking the delete button should remove the item from the list
