PHP使用来自作曲家的自动加载器添加自定义命名空间

2022-01-14 00:00:00 namespaces php composer-php autoload

这是我的文件夹结构:

Classes
  - CronJobs
    - Weather
      - WeatherSite.php

我想从我的脚本中加载 WeatherSite 类.我使用带有自动加载功能的作曲家:

I want to load WeatherSite class from my script. Im using composer with autoload:

$loader = include(LIBRARY .'autoload.php');
$loader->add('ClassesWeather',CLASSES .'cronjobs/weather');
$weather = new ClassesWeatherWeatherSite();

我假设上面的代码是添加命名空间和命名空间解析到的路径.但是当页面加载时我总是得到这个错误:

Im assuming the above code is adding the namespace and the path that namespace resolves to. But when the page loads I always get this error:

 Fatal error: Class 'ClassesWeatherWeatherSite' not found

这是我的 WeatherSite.php 文件:

Here is my WeatherSite.php file:

namespace ClassesWeather;

class WeatherSite {

    public function __construct()
    {

    }

    public function findWeatherSites()
    {

    }

}

我做错了什么?

推荐答案

你其实不需要自定义自动加载器，你可以使用 PSR-4.

You actually don't need custom autoloader, you can use PSR-4.

更新 composer.json 中的 autoload 部分:

Update your autoload section in composer.json:

"autoload": {
    "psr-4": {
        "Classes\Weather\": "Classes/CronJobs/Weather"
    }
}

解释一下:它是 {"Namespace\":"directory to be found in"}

别忘了运行 composer dump-autoload 来更新 Composer 缓存.

Don't forget to run composer dump-autoload to update Composer cache.

那么你可以这样使用它:

Then you can use it like this:

include(LIBRARY .'autoload.php');

$weather = new ClassesWeatherWeatherSite();
