What are the potential pitfalls of using outdated MySQL functions like mysql_insert_Id in PHP for database operations?

Using outdated MySQL functions like mysql_insert_id in PHP for database operations can lead to security vulnerabilities and compatibility issues with newer versions of MySQL. It is recommended to use the improved MySQLi or PDO extensions in PHP for database operations instead. 

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

// Perform an INSERT query
$mysqli->query("INSERT INTO table_name (column_name) VALUES ('value')");

// Get the last inserted ID
$last_id = $mysqli->insert_id;

// Close the connection
$mysqli->close();

echo "Last inserted ID: " . $last_id;
