How can PHP beginners effectively transition from using files to storing data in databases like SQLite for better performance?

To transition from using files to storing data in databases like SQLite for better performance, beginners can start by creating a SQLite database and connecting to it using PHP. They can then modify their existing file-based data handling functions to interact with the SQLite database instead. This will improve performance by allowing for faster data retrieval and manipulation. 

// Connect to SQLite database
$db = new SQLite3('database.db');

// Example of inserting data into SQLite database
$name = 'John Doe';
$email = 'john.doe@example.com';
$sql = "INSERT INTO users (name, email) VALUES ('$name', '$email')";
$db->exec($sql);

// Example of retrieving data from SQLite database
$result = $db->query('SELECT * FROM users');
while ($row = $result->fetchArray()) {
    echo $row['name'] . ' - ' . $row['email'] . '<br>';
}

// Close database connection
$db->close();
