What are the advantages of switching from mysql_* functions to PDO in PHP for database queries, and how can this improve the efficiency of data retrieval processes?

Switching from mysql_* functions to PDO in PHP for database queries offers several advantages such as improved security through prepared statements, support for multiple database systems, and easier error handling. This can improve the efficiency of data retrieval processes by providing a more secure and flexible way to interact with databases. 

// Using PDO for database queries
try {
    $pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
    $stmt = $pdo->prepare('SELECT * FROM mytable WHERE id = :id');
    $stmt->bindParam(':id', $id, PDO::PARAM_INT);
    $stmt->execute();
    $result = $stmt->fetchAll(PDO::FETCH_ASSOC);
    
    // Process the retrieved data
    foreach($result as $row) {
        // Do something with $row
    }
} catch(PDOException $e) {
    echo 'Error: ' . $e->getMessage();
}
