To install the Ivory JSON builder library, 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 library in your composer.json
file:
$ composer require egeloen/json-builder
Composer will automatically download your dependencies & create an autoload file in the vendor
directory.
So easy, you just have to require the generated autoload file and you are already ready to play:
<?php
require __DIR__.'/vendor/autoload.php';
use Ivory\JsonBuilder;
// ...
The Ivory JSON Builder library follows the PSR-4 Standard. If you prefer install it manually, it can be autoload by any convenient autoloader.
