如何在不使用“使用"的情况下加载类但就像我用过它一样称呼它 [英] How to have class loaded without using "use" but call it as if I used it
问题描述
我研究了这两个来源，但没有一个对我有用.
I have studied these 2 sources, but none of those works for me.
http://www.yiiframework.com/doc-2.0/guide-concept-autoloading.html
我创建了自定义帮助程序类，我希望将其包含在应用程序的每个模型、控制器和视图中.我使用的是 Yii2 高级应用程序版本 2.0.11，我使用的 IDE 是 PHPStorm
I have created custom helper class which I want to include in every model, controller and view in my application. I am using Yii2 advanced app version 2.0.11, IDE I am using is PHPStorm
问题:
我想要实现的是在每个类开始时不使用 use 关键字，但仍然能够简单地调用 AppHelper::myMethod()在模型、控制器和视图中.这怎么可能?
What I want to achieve is to not use use keyword at the beggining of every class but still be able to simply call AppHelper::myMethod() in models, controllers and views.
How is that possible?
我最接近的是使用这个解决方案 https://stackoverflow.com/a/35160997/5395463
Closest I got it working was using this solution https://stackoverflow.com/a/35160997/5395463
所有其他解决方案对我都不起作用.我收到如下错误:
All other solutions did not work for me. I am getting errors like:
PHP Fatal Error – yii\base\ErrorException
Class 'frontend\controllers\AppHelper' not found
当我不包含 use commons\commands\AppHelper;或者当不使用命名空间时，因为他们建议使用其他设置:
when I simply dont include use commons\commands\AppHelper;
or when not using namespace as they suggest there with other settings:
Fatal error: Uncaught exception 'yii\base\UnknownClassException'
with message 'Unable to find 'common\commands\AppHelper'
in file: C:\xampp\htdocs\domain.com\web\common/commands/AppHelper.php.
Namespace missing?' in ...
解决方案:
感谢您的回复，我终于搞定了.https://stackoverflow.com/a/42330631/5395463 解决方案最适合我.因此，我从该类中删除了 namespace，但将其保留在 common\commands 文件夹中，将 require 添加到 frontend/web/index.php 和 backend/web/index.php 文件(不确定我是否也应该将它添加到 root 中的 yii 文件中，我没有，到目前为止它仍然运行良好)，并进行了更改从 AppHelper::myMethod() 到 \AppHelper::myMethod() 的类调用看起来现在一切正常.
Thanks for your responses, I got it working finaly. https://stackoverflow.com/a/42330631/5395463 solution works best for me.
So I removed namespace from that class, but left it in common\commands folder, added require to frontend/web/index.php and backend/web/index.php files (not sure if I should add it to yii file in root too, I didnt, so far it is working good anyways), and changed calls of class from AppHelper::myMethod() to \AppHelper::myMethod() looks like eveything is working now.
推荐答案
不懒惰的程序员的解决方案:
Solution for not lazy coders:
- 用你的类创建组件，这样你就可以像
\Yii::$app->my_component 一样使用它 - 即使这太多了，而且您的 IDE 比 Windows 记事本更好，请准备宏为您打印此内容
懒惰程序员的解决方案:
Solution for lazy coders:
- 将您的类保存在没有命名空间的单个 PHP 文件中.
修改您的入口脚本以包含此类 - 即对于基本项目模板，它是
/web/index.php；添加到那里
require(__DIR__ . '/path/to/MyClass.php');
对于高级项目模板，请正确修改.
For Advanced Project Template modify it properly.
