What steps can be taken to ensure the security of dynamically loaded content in PHP?

To ensure the security of dynamically loaded content in PHP, it is important to sanitize user input and validate any external data before using it in your application. This can help prevent common security vulnerabilities such as SQL injection, cross-site scripting (XSS), and remote code execution. 

// Sanitize and validate dynamically loaded content
$dynamic_content = isset($_GET['content']) ? $_GET['content'] : ''; // Get the dynamically loaded content
$allowed_content = ['page1', 'page2', 'page3']; // Define an array of allowed content

if (in_array($dynamic_content, $allowed_content)) {
    include($dynamic_content . '.php'); // Load the content if it is allowed
} else {
    echo 'Invalid content'; // Display an error message if the content is not allowed
}
