/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.*"

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.

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

You have to mention Base Path of your classes that need to be autoloaded:

{
    "autoload": {
        "psr-4": {
            "MyApp\\": "src/MyApp/"
        }
    },
    "require": {
        "cboden/ratchet": "^0.4.0",
        "react/zmq": "0.2.*|0.3.*"
    }
}

And run

Composer dump-autoload
