What are some potential pitfalls when dynamically including components in PHP, as seen in the code provided?

One potential pitfall when dynamically including components in PHP is the risk of including user input without proper validation, which can lead to security vulnerabilities such as code injection. To solve this issue, always sanitize and validate user input before using it in dynamic includes to prevent malicious code execution. 

// Example of including a component safely by validating user input
$component = $_GET['component'];

// Validate the component name to prevent arbitrary file inclusion
$allowed_components = ['header', 'footer', 'sidebar'];
if (in_array($component, $allowed_components)) {
    include $component . '.php';
} else {
    // Handle invalid component names accordingly
    echo 'Invalid component requested';
}
