Connecting with PDO in the PHP & Databases with PDO

Sorry about the late reply. I tried it myself, and it seems to working great for me. Here are the steps I took:

1. Create a new workspace using the PHP5 environment. (important)
2. Create an index.php file and paste in the code at the bottom of this answer.
3. Create a file called database.db in the same folder as index.php.
4. Either run php index.php in your console or click the eye icon in the upper-right corner of your workspace.

Hope that helps!

The code for index.php:

<?php

ini_set("display_errors", "On");

$db = new PDO("sqlite:./database.db");
var_dump($db);

exit;

?>

I am having the same problem. I contacted the team at treehouse and it seems they expect the forum to solve a problem that is very likely on their side. I would like to be able to follow this tracks as intended :(

Is there a solution for this yet?
Using .open in the sqlite3 console still gives the following error: Error: unknown command or invalid arguments: "open". Enter " .help" for help

It is from this video: https://teamtreehouse.com/library/php-databases-with-pdo/getting-started-with-pdo/introductions

Ran into the same problem.

I'm fairly confident that Treehouse has not included databases (and necessary extensions like PDO) with Workspaces, simply because of the amount of effort it would take.
