MySQLi PHP extension

[Ingolme]

PHP's manual states that the MySQL extension is deprecated, you can see it on any of the mysql function references as in the following page:http://es.php.net/manual/en/function.mysql-connect.php

Use of this extension is discouraged. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API for more information.Alternatives to this function include:

• mysqli_connect()
• PDO::__construct()

I think it would be good if W3Schools changed or appended new information to their PHP tutorial about the MySQLi extension since it seems to be the most commonly used alternative. Maybe the object-oriented style might not be good to teach, as object-oriented programming would need to be explained in the tutorials, but MySQLi does have a procedural style as well.
