PHP Fatal error: Class 'PDO' not found

I have this PHP function which has been working very well until i reinstalled my dev system:

function connectDB($database, $username, $password) {

    $DSN = "mysql:host=localhost;dbname=$database";

    try {
        $DBH = new PDO($DSN, $username, $password); <--- LINE 10
        return $DBH;
    }
    catch(PDOException $e) {
        die("Could not connect to the database.\n");
    }
}

And i'm getting the error:

PH开发者_开发技巧P Fatal error:  Class 'PDO' not found in /var/www/im/tools.php on line 10

I checked phpinfo() and PDO is enabled:

PDO drivers : mysql

PDO Driver for MySQL version: 5.1.54

The interesting thing is that the interaction with th MYSQL database is ok, but i'm still getting the error when debugging.

I'm puzzled about this error! My system is Ubuntu 11.04 + NGINX + PHP 5.3

Any tip to get rid of it? Thanks!

Are you using namespaced code? Maybe you need to use \PDO class then?

This can also happen if there is a php.ini file in the web app's current working directory. If one has been placed there to change certain settings, it will override the global one.

To avoid this problem, don't use a php.ini change settings; instead, do this in the vhost declaration or a .htaccess file with 'php_flag'.
