Script tries to download instead of display... working with PDO

[Darren884]

Hi before it gave an error that I didn't have the PostGreSQL driver for PDO so I installed it through the command line and changed my pdo.ini file to include it. After I went back to this script and it would not display it would just try to download from firefox. Can someone please tell me what is wrong? Here is the code:

<?php

// Include The Configuration
require_once('configuration.php');

// Database Class
class Database {
    // Class Variables
    public $status;
    private $dbh;

    // Connect To The Database
    public function __construct($dsn) {
        try {
            $dbh = new PDO($dsn);
            $this->status = 'Connected!';
        } catch (PDOException $e) {
            $this->status = 'Connection failed: ' . $e->getMessage();
        }
    }

    // Display The Status
    public function __toString() {
        return $this->status;
    }
}

$database = new Database($dsn);
echo $database;

?>
