Making a composer.json configuration file.

Its important to note that its just normal json file, named composer.json, that is placed in the same folder you will call composer to install packages.

{
    "require": {
        "php": ">=5.5",
        "zendframework/zendframework": "~2.5",
        "doctrine/doctrine-orm-module": "dev-master",
        "doctrine/doctrine-module": "^1.2"
    }
}

To install packages defined in Json configuration file

$ composer install

Fortunately Composer gives us, for free, an Autoloader file.

To start using it just require it and start instantiating you objects!

require_once 'vendor/autoload.php';

$em = new Zend\EventManager\EventManager();
print_r(get_class_methods($em));
