undefuned class MongoClient...

Heya...

[env]
Have the newest versions of php/mongo/mongo-php installed...
[phpstorm]
Have invalidated my cache and re-started...
Have added "*.class" to my PHP file extensions...


PHPStorm still reports MongoClient as undefined...  (executing MongoClient call and methods from the cli without issue so I know the install is ok)

Little yellow squares are messing with my OCD...

Any suggestions?

Thanks!
