Which version of CodeIgniter am I currently using?

Quick question.

Is there something similar to a phpinfo() - that would display the version for CodeIgniter?

Thanks.

Please check the file "system/core/CodeIgniter.php". It is defined in const CI_VERSION = '3.1.10';

For CodeIgniter 4, use the following:

<?php    
    echo \CodeIgniter\CodeIgniter::CI_VERSION;
?>

you can easily find the current CodeIgniter version by

echo CI_VERSION 


or you can navigate to System->core->codeigniter.php file and you can see the constant

/**
 * CodeIgniter Version
 *
 * @var string
 *
 */
    const CI_VERSION = '3.1.6';

Look for define in system/core/CodeIgniter.php:

define('CI_VERSION', '3.1.8');

You should try :

<?php
echo CI_VERSION;
?>

Or check the file system/core/CodeIgniter.php

From a controller or view - use the following to display the version:

<?php
   echo CI_VERSION;
?>

Yes, the constant CI_VERSION will give you the current CodeIgniter version number. It's defined in: /system/codeigniter/CodeIgniter.php As of CodeIgniter 2, it's defined in /system/core/CodeIgniter.php

For example, 

echo CI_VERSION; // echoes something like 1.7.1
