Run using PHP internal server and remote DB?

Is it possible to run this using foreman, thus using the environmental variables, and the DATABASE_URL variable locally? When I try this, I get the error Error establishing a database connection.

Here is how I'm doing it.

In my Procfile_dev file

web: php -S 127.0.0.1:80 -t ./

In my .env file:

AUTH_KEY=[ VALUE HERE ]
SECURE_AUTH_KEY=[ VALUE HERE ]
LOGGED_IN_KEY=[ VALUE HERE ]
NONCE_KEY=[ VALUE HERE ]
AUTH_SALT=[ VALUE HERE ]
SECURE_AUTH_SALT=[ VALUE HERE ]
LOGGED_IN_SALT=[ VALUE HERE ]
NONCE_SALT=[ VALUE HERE ]
DATABASE_URL=[ VALUE HERE ]
HEROKU_POSTGRESQL_BLUE_URL=[ VALUE HERE ]
AWS_ACCESS_KEY_ID=[ VALUE HERE ]
AWS_SECRET_ACCESS_KEY=[ VALUE HERE ]
SENDGRID_PASSWORD=[ VALUE HERE ]
SENDGRID_USERNAME=[ VALUE HERE ]

Then I run:

sudo foreman start -f Procfile_dev --env .env

I'm on OS X Yosemite using PHP 5.5 though Homebrew, with the php55-pdo-pgsql package installed.

I fixed this by changing part of wp-config.php. Originally (line 18):

// ** Heroku Postgres settings - from Heroku Environment ** //
$db = parse_url( $_ENV["DATABASE_URL"] );

Fix:

// ** Heroku Postgres settings - from Heroku Environment ** //
$db = parse_url( getenv("DATABASE_URL") );

Is there a reason all the other environment variables use getenv() but the database uses $_ENV?

Side note: I also added two more environment variables to the app and put the in wp-config.php like this,

define('WP_HOME',               getenv('WP_HOME'));
define('WP_SITEURL',            getenv('WP_SITEURL'));

These are then set to http://localhost/ in my .env file, and to my sites live domain on Heroku. This prevents Wordpress from redirecting to whatever URL values are in the database.
