PHP 致命错误:在/MyApp/chat-server.php 中找不到类“MyAppChat"

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

This is my file structure

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

<?php
use RatchetServerIoServer;
use MyAppChat;

#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.*"
    }
}

Vendor Folder is exist in this location

/var/www/src/MyApp/vendor/

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

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

解决方案

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.

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.

You can solve this issue in 3 different ways:

• 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
