Mongo class not found in Heroku PHP

Question

I am using Heroku PHP, and has added the MongoHQ addon.

But it gives an error "class Mongo not found" at the line $m = new Mongo();

What else do I need to setup mongo driver on Heroku?

Answer 1

It is now supported.

Follow the instructions at https://gist.github.com/1288447

Custom extensions can be added to /app/www/ext/ with your custom php.ini!

Answer 2

Heroku currently does not support Mongo PHP classes.

Yeah, you can add the MongoHQ add-on etc, but Mongo driver is still not available for PHP yet. This answer comes for Heroku support.
