You would need to include your MY_Controllerclass or auto-load it. I suggest you auto-load it by adding the following to your application/config/config.phpfile.
您需要包含您的MY_Controller类或自动加载它。我建议您通过将以下内容添加到application/config/config.php文件中来自动加载它。
function __autoload($class)
{
if (strpos($class, 'CI_') !== 0)
{
if (file_exists($file = APPPATH . 'core/' . $class . EXT))
{
include $file;
}
}
}

Make sure the filename is perfectly cased. Linux server is case-sensitive. So if the class name is My_Controller then the name of the file should be My_Controller.php
确保文件名大小写完美。Linux 服务器区分大小写。所以如果类名是 My_Controller 那么文件名应该是 My_Controller.php

$config['subclass_prefix'] = "MY_"
$config['subclass_prefix'] = "MY_"
check that in config.phpand of course you should use it in Controller Name Like MY_Controller.phpand Named "class MY_Controller...."
检查，config.php当然你应该在 Controller Name LikeMY_Controller.php和 Named "class MY_Controller ...." 中使用它

in config/config.php
在config/config.php
/* load class in core folder */
function my_load($class) {
if (strpos($class, 'CI_') !== 0) {
if (is_readable(APPPATH . 'core' . DIRECTORY_SEPARATOR . $class . '.php' )) {
require_once (APPPATH . 'core' . DIRECTORY_SEPARATOR . $class . '.php');
}
}
}
spl_autoload_register('my_load');

Late with this answer, but I got the
这个答案迟到了，但我得到了
"Fatal error: Class ‘MY_Controller' not found" error
“致命错误：未找到‘MY_Controller’类”错误
when I had a controller (.php) file by the same name at the web root instead of the application/controllers directory.
当我.php在 web 根目录而不是 application/controllers 目录中有一个同名的控制器 ( ) 文件时。
Don't know how it got there, actually, but the problem went away when I deleted it.
不知道它是如何到达那里的，实际上，但是当我删除它时问题就消失了。
