How can PHP developers avoid redundancy and improve code efficiency when creating multiple PHP files for each event in a calendar application?

To avoid redundancy and improve code efficiency when creating multiple PHP files for each event in a calendar application, PHP developers can use a single PHP file to handle all event-related operations by passing parameters or using a switch statement to determine the specific event being accessed. This approach reduces the number of files needed and centralizes the logic for handling events, making the code easier to maintain and update.

<?php

// Assume the calendar application passes an event ID as a parameter
$event_id = $_GET['event_id'];

// Switch statement to handle different events based on the event ID
switch ($event_id) {
    case 1:
        // Code to handle event 1
        break;
    case 2:
        // Code to handle event 2
        break;
    // Add more cases as needed for additional events
    default:
        // Default case if event ID is not recognized
        break;
}

?>
