Are there any security considerations to keep in mind when implementing a feature to automatically delete advertisements after a certain time in PHP?

When implementing a feature to automatically delete advertisements after a certain time in PHP, it is important to consider security measures to prevent unauthorized access or manipulation of the deletion process. One way to enhance security is to implement proper authentication and authorization checks to ensure that only authorized users can trigger the deletion of advertisements based on the specified time criteria. 

// Check if the user is authenticated and authorized to delete advertisements
if($user_authenticated && $user_authorized) {
    // Code to automatically delete advertisements after a certain time
    $current_time = time();
    $delete_time = strtotime($advertisement['delete_time']);
    
    if($current_time >= $delete_time) {
        // Code to delete the advertisement
        deleteAdvertisement($advertisement_id);
    }
}
