Will my PHP application work with Heroku's ClearDB MySql resource? - mysql

Question

I am new to both php and Heroku and I have run into a bit of a problem. Currently my application is running fine on my xxamp testing server with mysql however when I try to host it on Heroku, there is no connection to the MySql server.
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [2003] Can't connect to MySQL server on '127.0.0.1' (111)' in /app/www/pdo_testdb_connect.php:6 Stack trace: #0 /app/www/pdo_testdb_connect.php(6): PDO->__construct('mysql:host=127....', 'd2398h23d9d82j3', '8dj1292d3') #1 /app/www/all.php(6): testdb_connect() #2 {main} thrown in /app/www/pdo_testdb_connect.php on line 6
Does ClearDB not work with PHP? Any suggestions would be much appreciated as I've sort of hit a brick wall.

Answer 1

Here is the php integration of Cleardb with Heroku:
define ('DB_USER','xxxxxxxxxxxxxxxx');
define ('DB_PASSWORD','yyyyyyyyyyyyyy');
define ('DB_HOST','us-cdbr-east.cleardb.com');
define ('DB_NAME','heroku_zzzzzzzzzzzzzzzzzz');
Take the params by going in Git and typing heroku config.
You will see a CLEARDB_DATABASE_URL
Here is how to decode it:
mysql://xxxxxxxxxxxxxx:yyyyyyyy#us-mm-auto-dca-01.cleardb.com/heroku_zzzzzzzzzzzzzzz
Interestingly enough, in the official documentation they provide only a Ruby example but nothing about php..

Answer 2

heroku config | grep CLEARDB_DATABASE_URL
