To install the Ivory Serializer bundle, you will need Composer. It's a PHP 5.3+ dependency manager which allows you to declare the dependent libraries your project needs and it will install & autoload them for you.
Composer comes with a simple phar file. To easily access it from anywhere on your system, you can execute:
$ curl -s https://getcomposer.org/installer | php
$ sudo mv composer.phar /usr/local/bin/composer
Require the bundle in your composer.json
file:
$ composer require ivory/serializer-bundle
Then, add the bundle in your AppKernel
:
// app/AppKernel.php
public function registerBundles()
{
return [
// ...
new Ivory\SerializerBundle\IvorySerializerBundle(),
];
}
