Are there any recommended PHP functions or methods for exporting and importing user input data in scripts?

When working with user input data in PHP scripts, it is important to properly sanitize and validate the data to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. One recommended approach for exporting and importing user input data is to use PHP's built-in functions like `json_encode()` and `json_decode()` to serialize and deserialize the data. 

// Export user input data
$userData = [
    'name' => $_POST['name'],
    'email' => $_POST['email'],
    'message' => $_POST['message']
];

$exportedData = json_encode($userData);
file_put_contents('user_data.json', $exportedData);

// Import user input data
$importedData = file_get_contents('user_data.json');
$userData = json_decode($importedData, true);

echo 'Name: ' . $userData['name'] . '<br>';
echo 'Email: ' . $userData['email'] . '<br>';
echo 'Message: ' . $userData['message'] . '<br>';
