I used the following PHP code to connect to MongoDB:

$m = new MongoClient("mongodb://localhost:27017");

However, I am getting the following error:

Fatal error: Uncaught exception 'MongoConnectionException' with message 'Failed to connect to: localhost:27017: Unknown error'

I tried lot of connection string possibilities that are posted in various blogs; nothing helps. Does anyone have any ideas?

In my case McAfee firewall leads to this problem. When i 'Turn-Off' firewall it started working..
