In what scenarios would using PDO over mysqli be more advantageous for handling database connections in PHP scripts on a Linux server?

Using PDO over mysqli can be more advantageous in scenarios where you need to work with multiple database systems, as PDO supports a wider range of database drivers. Additionally, PDO provides a more consistent interface for database access, making it easier to switch between different databases without changing your code significantly. PDO also supports prepared statements by default, which can help prevent SQL injection attacks. 

// Using PDO to connect to a MySQL database
$dsn = 'mysql:host=localhost;dbname=mydatabase';
$username = 'username';
$password = 'password';

try {
    $pdo = new PDO($dsn, $username, $password);
    // Set PDO to throw exceptions on error
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    echo "Connected to database successfully";
} catch (PDOException $e) {
    echo "Connection failed: " . $e->getMessage();
}
