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

Question

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 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.*"
    }
}

Vendor Folder is exist in this location

Answer 1

If you don't have the composer.json file and the vendor folder at root, it won't work. Also, don't touch the vendor folder (and subfolders). The folder structure must be like this:

/composer.json
/composer.phar
/vendor/[misc]
/src/MyApp/Chat.php

Finally, after updating the composer.json, make sure to run an update:

php composer.phar update

This way it will work.
