PHP - how to make MySQL insert query with PDO?

In PHP it is possible to make SQL INSERT query with PDO in following way.

1. INSERT query with PDO example

<?php

	if(isset($_GET['name']) && isset($_GET['role']))
	{
		$name = $_GET['name'];
		$role = $_GET['role'];

		$db_name = 'test';
		$db_host = '127.0.0.1'; // 'localhost'
		$db_username = 'root';
		$db_password = 'root';

		$dsn = 'mysql:dbname=' . $db_name . ';host=' . $db_host . ';charset=utf8';
		$pdo = new PDO($dsn, $db_username, $db_password);

		$query = 'INSERT INTO `users` (`name`, `role`) VALUES (:name, :role)';
		$statement = $pdo->prepare($query);

		if($statement === FALSE)
			die('Query preparation error!');

		$parameters = array(
			'name' => $name,
			'role' => $role
		);

		if($statement->execute($parameters))
		{
			$count = $statement->rowCount();

			if($count > 0)
			{
				$id = $pdo->lastInsertId('id');
				
				echo 'Last added user has id ' . $id . '.';
			}
			else
				echo 'Add user operation error!';
		}
		else
			echo 'Query execution error!';
	}
