Only start session if hasn't already been started

[dwightwatson]

On 3.0-dev I get a notice warning that a session has already been started, even though the only call to session_start() in the app is the one in the Session_native.php file.

This will only call session_start() if the session does not exist, to prevent a warning.

I have never seen this warning. Can you give more information about your PHP environment, and the exact warning text?

This is the error that I get:

A PHP Error was encountered

Severity: Notice

Message: A session had already been started - ignoring session_start()

Filename: drivers/Session_native.php

Line Number: 113

Backtrace:

File: /nfs/c09/h01/mnt/128773/domains/timetableexchange.com/application/core/MY_Controller.php
Line: 66
Function: __construct

File: /nfs/c09/h01/mnt/128773/domains/timetableexchange.com/html/index.php
Line: 277
Function: require_once

The __construct() function in MY_Controller simply calls parent::__construct() and then loads a model. Running PHP 5.3.15 (Media Temple (gs)).
