Unable to find Mongo class in Connection.php Symfony 2

Question

This is quite an often occurring error, but since I tried a lot of stuff to fix it, I'm kind of getting out of the ideas.

I have a symfony 2 with mongo DB. I have set up my composer.json file to download doctrine-mongo and doctrine-mongo-bundle,

"doctrine/mongodb-odm": "1.0.*@beta",
"doctrine/mongodb-odm-bundle": "3.0.*@beta",

In order to download this 2 modules, I needed to have mongo extension installed into PHP. I have both of them, mongo and mongodb, installed via brew

brew install php56-mongo
brew install php56-mongodb

I believe I have mongo extensions allowed as well, since when I write

php -m

I get this results

and you can see mongo there.

Also php -i returns info that mongo is enabled.

But when I'm trying to hit app_dev.php file in my project, I still get this:

ClassNotFoundException in Connection.php line 284: Attempted to load class "Mongo" from the global namespace. Did you forget a "use" statement?

I'm using a Mac OS X and have chmod 777 on

app/logs
app/cache 
web/

recursively.

Do you have any idea what can trigger this ? Thank you.

Answer 1

PHP Cli and fpm/apache doesn't use the same configuration, which means your php -m may be not accurate.

What you can do is call http://php.net/manual/en/function.extension-loaded.php inside your php entry point file on your server and make sure its loaded. Restarting the processes can help as well.
