在为Composer创建包时，如何加载依赖项？

Question

I've made packages for NPM and I know the drill there. You simply list your dependencies and then require() them. Node searches node_modules , finds the package, loads it and you're good to go.

How does that work in PHP, though? My dependency is PoParser . I know I can just do:

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

But when I publish my package, I wouldn't publish the third party dependency code, right? My package should only contain my code. At least that's the case with NPM.

So if I don't have that vendor folder when I publish my thing. How would I require my dependency? In Node, require() does that hard work. How would I do it here?

Here's my folder structure, if that helps:

vendor
    /composer
        ...
    /sepia
        /po-parser
            ...
            /src
                /Sepia
                ...
                // dependency classes
                ...
            ...
    autoload.php
composer.json
composer.lock
MyThing.class.php
Other.class.php

Composer will handle that for you. Put your dependencies inside the composer.json file and when you require your project it will download the dependencies too.
