Solution 1 - Php
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
Solution 2 - Php
Look for define in system/core/CodeIgniter.php:
define('CI_VERSION', '3.1.8');
Solution 3 - Php
You should try :
<?php
echo CI_VERSION;
?>
Or check the file system/core/CodeIgniter.php
Solution 4 - Php
From a controller or view - use the following to display the version:
<?php
echo CI_VERSION;
?>
Solution 5 - Php
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';
Solution 6 - Php
Please check the file "system/core/CodeIgniter.php". It is defined in const CI_VERSION = '3.1.10';
Solution 7 - Php
For CodeIgniter 4, use the following:
<?php
echo \CodeIgniter\CodeIgniter::CI_VERSION;
?>
