What are the advantages and disadvantages of using XML versus a database for storing and managing temporary data in a PHP application?

When deciding between using XML or a database for storing and managing temporary data in a PHP application, it's important to consider the advantages and disadvantages of each option. XML is more lightweight and easier to work with for small amounts of data, but it may not be as efficient for large datasets. On the other hand, a database like MySQL or SQLite offers better performance and scalability, but it requires more setup and maintenance. 

// Example of storing temporary data in XML
$xml = new SimpleXMLElement('<data></data>');
$xml->addChild('name', 'John Doe');
$xml->addChild('age', 30);

$xml->asXML('temp_data.xml');

// Example of storing temporary data in a database
$pdo = new PDO('mysql:host=localhost;dbname=test', 'username', 'password');
$stmt = $pdo->prepare('INSERT INTO temp_data (name, age) VALUES (:name, :age)');
$stmt->execute(['name' => 'John Doe', 'age' => 30]);
