Question

I managed to run MongoDB on Codeigniter using Alex Bilbie` library. The operations go well (connection, queries etc. ) but sometimes I get these PHP notices:

Message: Mongo::__construct() [mongo.--construct]: localhost:27017: pool get (0x4bfab20)

Filename: libraries/Mongo_db.php

Line Number: 1274
A PHP Error was encountered

Severity: Notice

Message: Mongo::__construct() [mongo.--construct]: localhost:27017: found in pool (0x4bfab20)

Filename: libraries/Mongo_db.php

Is there a way to get rid of these? or maybe hide them..as they don’t seem to mess up my pages in another way than splashing into the user’s screen.

EDIT

On a few pages though, I use the JQgrid and when the errors show up they mess up my HTTP response and render some messy data.

The specific notice messages here have been removed in the MongoDB PHP driver 1.2.11 or later (see PHP-431). Upgrading your MongoDB driver to the latest should remove the excessive notice logging.

General notes on proper settings for Code Igniter logging in production still apply…

The E_NOTICE level of error reporting is intended to warn you about possible bugs or typos. It is typically only used as a development setting rather than for production messages.

The default error_reporting setting in PHP4 and PHP5 is actually set to ignore these:

E_ALL & ~E_NOTICE

The Code Igniter index.php has an application environment setting which normally shows all errors for development and suppresses error reporting for testing and production. You should set this appropriately:

define('ENVIRONMENT', 'production');

If you actually want to capture these messages for a production environment you should update the production settings in your index.php so that instead of error_reporting(0) you have:

• error_reporting() set to appropriate level of detail
• display_errors off
• log_errors on
• error_log path set

For example, in index.php you could have:

case 'production':
    error_reporting(E_ALL);
    ini_set('display_errors','Off');
    ini_set('log_errors','On');
    ini_set('error_log','/var/log/php5.log');
break;

That way the messages/notices will still be saved to the error_log if you want to review them, but they will not be shown to the end user.
