未找到PHP类(但它存在)

Question

我意识到这个问题几乎肯定是通过前面问题中的八百万个建议中的一个来解决的，但是我找不到问题或解决方案。

我在CodeIgniter 3中有一个PHP7.3应用程序，我使用的是Algolia搜索客户端PHP。

我已通过npm安装并设置了composer requirements.

• I，它更新了composer以要求程序包

• 我已经验证了使用名称空间(从Algolia文档复制和粘贴并通过PHPstorm验证路径是否正确)的文件

• 的存在。

• --我在这些文件中不使用PHP短标签，也不能在应用程序中验证其他类的存在，但是，供应商目录中似乎没有任何东西(指示了一个编写器问题)-

• -我尝试使用- did()而不是使用- did，而不是解决我已经重新启动Apache、运行编写器转储-autoload和通过npm (不一定按顺序)的

• 更新所有供应商包-

• - PHP

中没有这些请求。

在我的类中使用(类的其余部分如预期的那样)

<?php

use Algolia\AlgoliaSearch\InsightsClient;

class Click_model extends CI_Model {
   function conversion() {
       if ( !class_exists('InsightsClient') ) die('There is no hope!');
   }
}

Answer 1

请确保您的文件名和类名必须匹配。此外，请尝试使用编程标准，因为类有一个--在定义类名时始终使用pascal大小写，例如FileManager、AlgoliaSearch等

最后，您没有导入要扩展的类CI_Model。如果这是上面提到的包中的类，那么通过将/CI_model放在import语句的末尾来确保它是导入的。

Answer 2

最后，我发现这是一个与自动驾驶有关的问题。通过添加下面的第一行，use语句将正确解析，使控制器可以使用它。

require FCPATH."/vendor/autoload.php";
use Algolia\AlgoliaSearch\SearchClient;
