Switching to memcache for sessions

#1
Hello,

I need to save sessions to memcache instead of files in my local instance of codeignitor.

This is what I did:
Step 1 : updated config.php
$config['sess_driver'] = 'memcached';
$config['sess_save_path'] = 'localhost:11211';


Step 2: update php.ini
session.save_handler=memcached
session.save_path="tcp://localhost:11211?persistent=1&weight=1&timeout=1&retry_interval=15" 

Step 3: Restart apache

This works fine.

Now when I need to deploy this to the server, I came to know that I am not allowed to update the ini settings because Im using shared services. 

My question is: how do I set session.save_handler and session.save_path via code in codeignitor and not depend on updating php.ini of the server?

You might be able to do it in an .htaccess file in your doc root.

I don't believe that you need to set php.ini directly.

First of all, CodeIgniter will set the session.save_handler based on $config['sess_driver'] . CodeIgniter would ignore the php.ini setting for session.save_handler as it sets up its own SessionHander class to attend to all the open/close, read/write, etc chores for managing Sessions.

Second, session.save_path can be and is set via
PHP Code:
ini_set('session.save_path'config_item('sess_save_path')); 

In short, your $config settings should be all you need.

IMO, find a different ISP because neither of those items should affect a shared server that is properly set up.

Thanks for replying to my query!

I see that in Session_files_driver it does;
ini_set('session.save_path', $this->_config['save_path']); // setting the php.ini

But does not do anything similar in Session_memcache_driver.
I tried adding it in the __contruct but that dint work.

Im using CI version 3.3.0

True it does not call ini_set('session.save_path', ..., but it doesn't need to.
The Memcached driver does not use 'session.save_path' from php.ini. It only needs/uses a value from $this->_config['save_path'].

Is it not working using just the $config items?

Thanks for answering my question!

How do I verify that my sessions I being saved in memcache and not in files.
What is the key used in codeignitor to save sessions?
