How can storing the sessionID in a database enhance the security of a PHP application?

Storing the sessionID in a database enhances the security of a PHP application by preventing session hijacking and providing a centralized location for managing sessions. By storing session data in a database, you can easily track and invalidate sessions, preventing unauthorized access to user accounts. 

<?php
session_set_save_handler(
    function ($savePath, $sessionName) {
        // Custom session save handler to store session data in a database
    },
    function ($sessionId) {
        // Custom session read handler to retrieve session data from a database
    },
    function ($sessionId, $data) {
        // Custom session write handler to update session data in a database
    },
    function ($sessionId) {
        // Custom session destroy handler to remove session data from a database
    },
    function ($maxLifetime) {
        // Custom session garbage collection handler to clean up expired sessions in a database
    }
);

session_start();
?>
