PHP致命错误：在/MyApp/chat-server.php中找不到类“ MyApp\Chat” [英] PHP Fatal error: Class 'MyApp\Chat' not found in /MyApp/chat-server.php

问题描述

我正在尝试运行Ratchet应用程序演示，但无法执行文件

I am trying to run the Ratchet application demo but I can't execute the file

这是我的文件结构

/var/www/src/MyApp/
/var/www/src/MyApp/chat.php
/var/www/src/MyApp/chat-server.php

<?php
use Ratchet\Server\IoServer;
use MyApp\Chat;

#require "chat.php";

    require 'vendor/autoload.php';

    $server = IoServer::factory(
        new Chat(),
        8080
    );

    $server->run();

/var/www/src/MyApp/composer.json

{
    "autoload": {
        "psr-0": {
            "MyApp": "src"
        }
    },
    "require": {
        "cboden/Ratchet": "0.3.*"
    }
}

此位置存在供应商文件夹

Vendor Folder is exist in this location

/var/www/src/MyApp/vendor/

每当我在终端中执行聊天服务器文件时，都会出现以下错误

Whenever I am executing the chat-server file in terminal I got the following error

PHP Fatal error:  Class 'MyApp\Chat' not found in /MyApp/chat-server.php

This question was asked but still no answer for that question too Class 'MyChat\Chat' not found in C:\wamp\www\bin\chat-server.php

推荐答案

自动加载的主要路径是composer.json文件的位置，因此如果该文件位于 / var / www / src / MyApp / ，自动加载将以此为基础。

The main path for the autoloading is the location of the composer.json file, so if that lives in /var/www/src/MyApp/, the autoloading will use that as a base.

在您的情况下，您说 MyApp 命名空间可以是在 src 目录（即 / var / www / src / MyApp / src ）中找到。这是不正确的，因为文件 /var/www/src/MyApp/src/MyApp/Chat.php 不存在。

In your case, you say the MyApp namespace can be found in the src directory (which means /var/www/src/MyApp/src). That's not true, since the file /var/www/src/MyApp/src/MyApp/Chat.php does not exists.

您可以通过3种不同方式解决此问题：

You can solve this issue in 3 different ways:

• 移动 composer.json -您可以将 composer.json 文件移动到 / var / www ，以便能够将其用作基础；


• 更新自动加载（使用PSR-4）-您也可以使用PSR-4代替PSR-0并将其配置为 autoload：{ psr-4：{ MyApp\\：}} ;



• 重组文件-您还可以将文件结构更改为：

• Moving composer.json - You can move the composer.json file to /var/www, to be able to use that as base;
• Updating autoloading (using PSR-4) - You can also use PSR-4 instead of PSR-0 and configure it as "autoload": { "psr-4": { "MyApp\\": "" } };

• Reorganizing your files - You can also change the file structure to:

/var/www/src/MyApp/
    src/MyApp/
            Chat.php
    composer.json
