What are the drawbacks of using the mysql_* functions in PHP, and what are the recommended alternatives?

The mysql_* functions in PHP are deprecated and not recommended for use due to security vulnerabilities and lack of support. It is recommended to use MySQLi (MySQL Improved) or PDO (PHP Data Objects) extensions for interacting with MySQL databases in PHP. 

// Using MySQLi extension
$mysqli = new mysqli("localhost", "username", "password", "database");
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Using PDO extension
$pdo = new PDO("mysql:host=localhost;dbname=database", "username", "password");
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
