谢谢你非常匹配！
定义了一个常量来确定/system/core/Codeigniter.php中的版本
define('CI_VERSION', 'x.xx')
Codeigniter的当前版本在 system/core/CodeIgniter.php 中定义。
您可以使用以下方法获取当前版本：
echo CI_VERSION;//outputs your current CI's version
对于查看代码点火器版本，您必须编写此代码
<?php
echo CI_VERSION;
?>
或者您可以检查文件system/core/CodeIgniter.php
对于检查代码点火器版本，您必须编写此代码
<?php
echo CI_VERSION;
?>
或者您可以检查文件system/core/CodeIgniter.php对于版本 3.xx
和检查文件 system/CodeIgniter.php 对于版本 4.xx
