This file will reside in the root level of the public folder (/public/confirmdelete.php), and it will be very similar to index.php. This file accomplishes the following tasks: • Ensures an event ID was passed and stored in the $id variable; sends the user to the main view otherwise. • Loads the initialization file. • Creates a new instance of the Calendar object. • Loads the return value of confirmDelete() into a variable, $markup. • Defines the $page_title and $css_files variables and includes the header. • Outputs the data stored in $markup. • Outputs the footer. 195
