IntelliJ IDEA 12 找不到 CodeIgniter 类，抛出错误

Question

我正在使用 IntelliJ IDEA 12 开发一个使用 CodeIgniter 框架的 PHP Web 应用程序。由于 CI 实例化对象和方法的方式，IDEA 认为它们在被调用时并不存在：

如您所见，在我尝试使用的每个 CodeIgniter 类/方法下，我都会遇到那些烦人的橙色曲线。

下面是 CI_Controller 类的代码，可以深入了解它们是如何创建对象的：

class CI_Controller {

    private static $instance;

    /**
     * Constructor
     */
    public function __construct()
    {
        self::$instance =& $this;

        // Assign all the class objects that were instantiated by the
        // bootstrap file (CodeIgniter.php) to local class variables
        // so that CI can run as one big super object.
        foreach (is_loaded() as $var => $class)
        {
            $this->$var =& load_class($class);
        }

        $this->load =& load_class('Loader', 'core');

        $this->load->initialize();

        log_message('debug', "Controller Class Initialized");
    }

    public static function &get_instance()
    {
        return self::$instance;
    }
}

有什么方法可以让 IntelliJ IDEA 忽略这些错误（但不是其他错误），或者让它自己找到对象？

注意：我曾经使用 PHPStorm，这是一个在 IntelliJ IDEA 平台上构建的 PHP IDE，它在 CodeIgniter 上做了同样的事情。

Answer 1

我通过关注this guide 解决了这个问题。它适用于 PHPStorm，但也适用于 IntelliJ IDEA（可能也是 WebStorm！）。其实很简单。基本回顾：

1. 在我的项目根目录中保存了以下 PHP 代码。它基本上只是一个 PHPDoc 注释：

2。在 IntelliJ IDEA 中找到 /system/core/controller.php 和 /system/core/model.php 并右键单击->标记为纯文本。

3。完毕！它工作得很好，没有更多的错误错误和代码完成！

Answer 2

这是对我有用的解决方案：https://github.com/Stunt/Codeigniter-autocomplete/

我正在使用 phpStorm，但我想它可以与 IDEA 一起使用。

无需将文件标记为纯文本。只需将 autocomplete.php 文件放入 application/config 文件夹即可。我怀疑 github 上的链接会变坏，但以防万一这是文件的内容。

CIv3 更新：如果您使用的是 CodeIgniter V 3.x，请改用它。

我不能把这一切归功于我。我找到了很多，但不记得在哪里。我确实需要添加一些以使其完整。
