管理多個(gè)應(yīng)用

默認(rèn)情況下，我們假設(shè)你只是用CodeIgniter來(lái)管理一個(gè)應(yīng)用，并將該應(yīng)用在 application 目錄下進(jìn)行構(gòu)建。 然而也存在這樣的可能性：多個(gè)應(yīng)用共享一個(gè)CodeIgniter的安裝目錄，甚至開(kāi)發(fā)者會(huì)將 application目錄進(jìn)行重命名或移動(dòng)位置。

重命名或遷移應(yīng)用程序目錄

如果你想重命名你的應(yīng)用文件夾或者移動(dòng) it to a different location on your server, other than your project root, open your main app/Config/Paths.php and set a full server path in the $appDirectory variable (at about line 38):

public $appDirectory = '/path/to/your/application';

You will need to modify two additional files in your project root, so that they can find the Paths configuration file:

• /spark runs command line apps; the path is specified on or about line 36:

  require 'app/Config/Paths.php';
  // ^^^ Change this if you move your application folder
  

• /public/index.php is the front controller for your webapp; the config path is specified on or about line 16:

  $pathsPath = FCPATH . '../app/Config/Paths.php';
  // ^^^ Change this if you move your application folder
  

單個(gè)CodeIgniter對(duì)應(yīng)運(yùn)行多個(gè)應(yīng)用

如果你想要讓多個(gè)不同的應(yīng)用來(lái)共享一次CodeIgniter的安裝文件，只需要將你的應(yīng)用目錄下的所有目錄都移動(dòng)到他們對(duì)應(yīng)的子目錄中即可。

舉例而言，加入你想要?jiǎng)?chuàng)建兩個(gè)應(yīng)用程序，命名為”foo”和”bar”，你可以將你的應(yīng)用目錄排列如下:

/foo
    /app
    /public
    /tests
    /writable
/bar
    /app
    /public
    /tests
    /writable
/codeigniter
    /system
    /docs

This would have two apps, “foo” and “bar”, both having standard application directories and a public folder, and sharing a common codeigniter framework.

The index.php inside each application would refer to its own configuration, ../app/Config/Paths.php, and the $systemDirectory variable inside each of those would be set to refer to the shared common “system” folder.

If either of the applications had a command-line component, then you would also modify spark inside each application’s project folder, as directed above.
