Is it advisable to continue using mysqli in PHP 7 or switch to PDO?

It is advisable to switch to PDO in PHP 7 as mysqli is not as versatile and secure as PDO. PDO offers a more consistent interface for accessing databases and supports multiple database systems, making it a better choice for future-proofing your code. 

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

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