Re: Chat example and dependencies

[cboden]

In your chat-server.php you must include the following line at the top of your script:

<?php
    require __DIR__ . '/vendor/autoload.php';

Hello everyone,

I'm trying to run the Chat example but php is not able to resolve the needed libraries. I have installed composer and I have created the composer.json file. Composer then downloads the libraries and place them under the folder vendor. But when I run:

php chat-server.php

I get: PHP Fatal error:  Interface 'Ratchet\MessageComponentInterface' not found in /home/luca/tmp/f3w/src/MyApp/chat.php on line 6

I think that there must be something wrong with my project structure, the folder/file structure is the following:

-src
--chat-server.php
--composer.json
--MyApp\chat.php

To run composer I use the following command: php /home/luca/bin/composer.phar install
What am I doing wrong?

Thanks in advance

This is because composer doesn't know how to load your "MyApp" namespace.  Your Chat.php (case sensitive) class should be in a folder (commonly named) /src (/src/MyApp/Chat.php).  Update your composer.json file to the following and then re-run composer.phar install:

{
    "autoload": {
        "psr-0": {
            "MyApp": "src"
        }
    },
    "require": {
        "cboden/Ratchet": "0.2.*"
    }
}

This is how it looks my chat-server.php. I forgot to mention that I even had to add require_once otherwise it would not find my chat.php class

<?php
require_once("MyApp/chat.php");
use Ratchet\Server\IoServer;
use MyApp\Chat;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

    require dirname(__DIR__) . '/vendor/autoload.php';

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

    $server->run();

I think I see your issue - it's your directory structure.  I lay mine out like this:

-bin

--chat-server.php

-composer.json

-src

--MyApp

----Chat.php

-vendor

--autoload.php

I have changed chat.php to Chat.php, I have the same composer.json, and I have tried to re-run the composer but I still get the same error:

PHP Fatal error:  Interface 'Ratchet\MessageComponentInterface' not found in /home/luca/tmp/f3w/src/MyApp/Chat.php on line 6

You need to wrap your class in a WsServer instance to speak the WebSocket protocol.

Thanks with this new structure it works.

However, I managed to test it only with telnet because with Javascript WebSocket it is not connecting. Is there a need of a special javascript library to connect?

You're PHP build is missing the cURL extension.

You are right, I forgot about it. However there is still a problem, when I try to connect with the html/javascript page the chat-server.php die with:

PHP Fatal error:  Call to undefined function Guzzle\Http\Curl\curl_version() in /home/luca/tmp/f3w/websocket/vendor/guzzle/http/Guzzle/Http/Curl/CurlVersion.php on line 47

Any idea?

There's a problem with your autoloader:

* You forgot to set MyApp in your composer.json file

* You forgot to include the composer autoloader

* Your Chat class is in the wrong spot

* Your Chat class is named incorrectly inside its file

this gave an error saying that composer.lock file had to be update

2. php /usr/local/bin/composer.phar list

to get help 

3. php /usr/local/bin/composer.phar update

4. php /usr/local/bin/composer.phar validate

then it works.

So its seems like composer.lock file was causing probs

riti thanks so much. Step 3 was what I needed after the hello world page instructed new content for the composer.json file.

Why don't you put this structure on the website ?

Think of the time we save.

Look at all the messages you receive asking for the same thing.

When you want to test a library you need a quick test script so you can decide if you'll go with it or not.

Any help will be appreciated.

Thank's.

Sander, make sure you have your MyApp namespace in composer.json, run `composer update`, and make sure you're including the autoload file in your chat-server.php file.
