Add justinrainbow/epub to your composer.json file.

{
    "require": {
        "justinrainbow/epub": "master-dev"
    }
}

Then just run the composer.phar install (or composer.phar update if you added this to an existing composer.json file).

wget http://getcomposer.org/composer.phar
php composer.phar install

Add the following to your deps file

[epub]
    git=http://github.com/justinrainbow/epub.git

After you have run the bin/vendors install script, add the following to your autoload.php file.

<?php

$loader->registerNamespaces(array(
    // ... other namespaces ...
    'ePub'  =>  __DIR__.'/../vendor/epub/src'
));

<?php

$reader = new \ePub\Reader();
$epub = $reader->load('my-book.epub');

printf("Title: %s\n", $epub->getMetadata()->get('title'));
