Codeigniter Disable Cache
提问by kaarch
I'm trying to learn Codeigniter and understand the basics so far, but as I try to test, it seems the cache is getting in the way. Normally when I test on localhost I make a change and instantly can see it in browser, but with Codeigniter it seems I have to wait ~1 minute for changes to be seen in browser. Is there a way to universally disable the Codeigniter cache so when developing changes happen immediately?
到目前为止，我正在尝试学习 Codeigniter 并了解基础知识，但是当我尝试进行测试时，似乎缓存正在妨碍您。通常，当我在 localhost 上进行测试时，我会进行更改并立即可以在浏览器中看到它，但是使用 Codeigniter 似乎我必须等待大约 1 分钟才能在浏览器中看到更改。有没有办法普遍禁用 Codeigniter 缓存，以便在开发更改时立即发生？

Just put this code in the __construct function of controller
只需将这段代码放在控制器的 __construct 函数中
$this->output->set_header('Last-Modified: ' . gmdate("D, d M Y H:i:s") . ' GMT');('Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0');
$this->output->set_header('Pragma: no-cache');
$this->output->set_header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

Just delete all the cached items in the application/cache folder:
只需删除 application/cache 文件夹中的所有缓存项目：

IFyou enabled the cache, you need to disable it (comment out the cache). Otherwise it may be your browser caching, you could force a SHIFT-F5 (in most browsers).
如果您启用了缓存，则需要禁用它（注释掉缓存）。否则它可能是您的浏览器缓存，您可以强制 SHIFT-F5（在大多数浏览器中）。
The cache will only work if you have it so defined in your controller etc; not randomly.
只有在控制器等中定义了缓存时，缓存才会起作用；不是随机的。

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class MY_Cacheoff extends CI_Cacheoff {
/**

function disable_cache() {
$this->set_header('Expires: Sat, 26 Jul 1997 05:00:00 GMT');
$this->set_header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
$this->set_header('Cache-Control: no-cache, no-store, must-revalidate, max-age=0');
$this->set_header('Cache-Control: post-check=0, pre-check=0', FALSE);
$this->set_header('Pragma: no-cache');
}
}
