Yes, the constantCI_VERSIONwill give you the current CodeIgniter version number. It's defined in: /system/codeigniter/CodeIgniter.phpAs of CodeIgniter 2, it's defined in /system/core/CodeIgniter.php
是的，该常量CI_VERSION将为您提供当前的 CodeIgniter 版本号。它定义在：/system/codeigniter/CodeIgniter.php从 CodeIgniter 2 开始，它定义在 /system/core/CodeIgniter.php
For example,
例如，
echo CI_VERSION; // echoes something like 1.7.1

Look for definein system/core/CodeIgniter.php:
寻找define在system/core/CodeIgniter.php：
define('CI_VERSION', '3.1.8');
