Eroare mysql

Stie cineva cum pot rezolva aceasta eroare :

Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /home/u770039586/public_html/config.php on line 6

Cod PHP:

---

<?php
$db_name ="a3900988_dire"; /** The name of the database for this install */
$dbusername = "a3900988_dire"; /** MySQL database username */
$dbpassword = "********"; /** MySQL database password */
$server = "localhost"; //** Probably don't need to change this */
$connection = mysqli_connect('server', 'dbusername', 'dbpassword', 'db_name') or die(mysql_error());
?>

---

Cod PHP:

---

$connection = mysqli_connect('server', 'dbusername', 'dbpassword', 'db_name');
if(mysqli_connect_errno())
{
   die(mysqli_connect_error());
} 


---

Daca tot faci trecerea la o noua interfata de accesa baza de date, mai bine treci direct la PDO.

Cod PHP:

---

error_reporting(E_ALL ^ E_DEPRECATED);

Oricum, prin eroarea de mai sus, php te anunta intr-un mod dragut ca nu mai vrea sa folosesti mysql_error. Sau orice incepe cu "mysql" si nu se termina cu "i" inainte de "_".
