If I try to run the following PHP code, I get a "Call to a member function query() on a non-object". Do you know why? I use the same code on another site (http://daveismyname.com/creating-a-blog-from-scratch-with-php-bp#.U6fdxPmSxmx), where it works just fine.

try{
$db = new PDO('mysql:host=localhost;dbname=try', $username, $password);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e) {
echo "I'm sorry, I'm afraid i cant do that.";
file_put_contents('PDOErrors.txt', $e->getMessage(), FILE_APPEND);
$db = null;
