My controller or application isn't namespaced. I was hoping to just be able to use that one package in one controller's action in a non-namespaced framework.

我的控制器或应用程序没有命名空间。我希望能够在非命名空间框架中的一个控制器的操作中使用那个包。

For CodeIgniter 3.x and composer, it's suggestedto just set $config['composer_autoload']to TRUEor a custom path in application/config/config.php.

对于笨3.x和作曲家，它的建议只是集$config['composer_autoload']到TRUE或自定义路径application/config/config.php。

It seems that CI assumes the vendordirectory is within the applicationdirectory. That wasn't my case. I did the following:

CI 似乎假定vendor目录在application目录中。那不是我的情况。我做了以下事情：

$config['composer_autoload'] = 'vendor/autoload.php';

$config['composer_autoload'] = 'vendor/autoload.php';

This is possible by just getting the order of loading correct:

这可以通过正确获取加载顺序来实现：

/*
 * --------------------------------------------------------------------
 * LOAD THE BOOTSTRAP FILE
 * --------------------------------------------------------------------
 *
 * And away we go...
 *
 */
// Composer Autoloader
require FCPATH . 'vendor/autoload.php';

require_once BASEPATH.'core/CodeIgniter.php';

/* End of file index.php */

EDIT: Damn, I just said pretty much exactly the same thing as @Tjorriemorrie

编辑：该死的，我刚刚和@Tjorriemorrie 说的几乎完全一样

If you've followed all the other directions correctly, all you need to do is add the following code near the very the endyour index.php file:

如果您正确地遵循了所有其他说明，那么您需要做的就是在 index.php 文件的末尾附近添加以下代码：

/*
 * --------------------------------------------------------------------
 * COMPOSER AUTOLOAD
 * --------------------------------------------------------------------
 */
include_once './vendor/autoload.php';

...just make sure you slot it in beforethe CodeIgniter Bootstrap file is called:

...只需确保在调用 CodeIgniter Bootstrap 文件之前将其插入：

/*
 * --------------------------------------------------------------------
 * LOAD THE BOOTSTRAP FILE
 * --------------------------------------------------------------------
 *
 * And away we go...
 *
 */
 require_once BASEPATH.'core/CodeIgniter.php';

Well in Codeigniter3.x you can easily do that by going into the application/config/config.php and look for this line

那么在 Codeigniter3.x 中，您可以通过进入 application/config/config.php 并查找这一行来轻松做到这一点

$config['composer_autoload'] = FALSE;

Make sure you set it to TRUE and right after it you require_once this:

确保将其设置为 TRUE 并在它之后您 require_once ：

require_once APPPATH.'vendor/autoload.php';

So you get something like this:

所以你会得到这样的东西：

/*
|--------------------------------------------------------------------------
| Composer auto-loading
|--------------------------------------------------------------------------
|
| Enabling this setting will tell CodeIgniter to look for a Composer
| package auto-loader script in application/vendor/autoload.php.
|
|   $config['composer_autoload'] = TRUE;
|
| Or if you have your vendor/ directory located somewhere else, you
| can opt to set a specific path as well:
|
|   $config['composer_autoload'] = '/path/to/vendor/autoload.php';
|
| Note: This will NOT disable or override the CodeIgniter-specific
|   autoloading (application/config/autoload.php)
*/
$config['composer_autoload'] = TRUE;
require_once APPPATH.'vendor/autoload.php';

Just make sure you have your vendor folder in the application folder and you are good to go.

只要确保您的应用程序文件夹中有您的供应商文件夹，您就可以开始了。

I recently found out that you can just set $config['composer_autoload'] = TRUE; and put your vendor folder in the application folder and that's it.

我最近发现你可以设置 $config['composer_autoload'] = TRUE; 并将您的供应商文件夹放在应用程序文件夹中，就是这样。

For those who would want your vendor folder outside the application folder. You can make it happen in this way: for example you want to place it in the root folder.

对于那些希望您的供应商文件夹位于应用程序文件夹之外的人。您可以通过这种方式实现：例如，您想将其放在根文件夹中。

TIP: it has been described in the comment already

提示：它已经在评论中描述了

$config['composer_autoload'] = '/path/to/vendor/autoload.php';

$config['composer_autoload'] = '/path/to/vendor/autoload.php';

/*
|--------------------------------------------------------------------------
| Composer auto-loading
|--------------------------------------------------------------------------
|
| Enabling this setting will tell CodeIgniter to look for a Composer
| package auto-loader script in application/vendor/autoload.php.
|
|   $config['composer_autoload'] = '/path/to/vendor/autoload.php';
|
| Note: This will NOT disable or override the CodeIgniter-specific
|   autoloading (application/config/autoload.php)
*/
$config['composer_autoload'] = FCPATH .'vendor/autoload.php';

Where FCPATH is codeigniter's defined constant for the root folder.

其中 FCPATH 是 codeigniter 为根文件夹定义的常量。

I guess this helps.

我想这有帮助。

You can add directly the Composer Autoloder in your controller:

您可以直接在控制器中添加 Composer Autoloder：

// Composer Autoloader
require FCPATH.'vendor/autoload.php';

There are two ways you can autoload the class file which is required using composer.

有两种方法可以自动加载使用 Composer 所需的类文件。

1. Add below line in index.php in the root directory.

   require FCPATH . 'vendor/autoload.php';
   

2. Or autoload directly in the controller where you want to use.
   

   defined('BASEPATH') OR exit('No direct script access allowed');
   
   require FCPATH . 'vendor/autoload.php';
   
   class Home extends CI_Controller {...}
   

1. 在根目录下的 index.php 中添加以下行。

   require FCPATH . 'vendor/autoload.php';
   

2. 或者直接在您要使用的控制器中自动加载。
   

   defined('BASEPATH') OR exit('No direct script access allowed');
   
   require FCPATH . 'vendor/autoload.php';
   
   class Home extends CI_Controller {...}

I'm using Kenjis codeigniter composer package, and it puts the vendor directory off of the root. Since there is no predefined constant (that I know of) for the root, I used the following:

我正在使用Kenjis codeigniter composer package，它将供应商目录置于根目录之外。由于根没有预定义的常量（我知道），因此我使用了以下内容：

$root = getcwd();
$config['composer_autoload'] = "$root/vendor/autoload.php";
