Requirements

Installation (Composer)

0. Install Composer

If you don't have Composer yet, download it following the instructions on http://getcomposer.org/ or just run the following command:

{
    "require": {
        "davefx/phplot-bundle": "dev-master"
    }
}

Now tell composer to download the bundle by running the command:

$ php composer.phar update noiselabs/nusoap-bundle

Composer will install the bundle to your project's vendor/noiselabs directory.

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...

    );
}
