How can PHP developers ensure the security of film presentations on their websites?

PHP developers can ensure the security of film presentations on their websites by implementing proper input validation and sanitization to prevent SQL injection and XSS attacks. Additionally, they should use secure file storage methods and access controls to protect the videos from unauthorized access. 

// Validate and sanitize input data
$film_id = filter_input(INPUT_GET, 'film_id', FILTER_SANITIZE_NUMBER_INT);

// Check if the user has permission to access the film
if(check_user_permission($film_id)) {
    // Display the film presentation
    echo "<video controls><source src='films/{$film_id}.mp4' type='video/mp4'></video>";
} else {
    // Display an error message
    echo "You do not have permission to access this film.";
}

function check_user_permission($film_id) {
    // Implement your logic to check if the user has permission to access the film
    // Return true if the user has permission, false otherwise
}
