Guzzle Iterator

Provides useful Iterators and Iterator decorators

• ChunkedIterator: Pulls out chunks from an inner iterator and yields the chunks as arrays
• FilterIterator: Used when PHP 5.4's CallbackFilterIterator is not available
• MapIterator: Maps values before yielding
• MethodProxyIterator: Proxies missing method calls to the innermost iterator

Installing via Composer

# Install Composer
curl -sS https://getcomposer.org/installer | php

# Add Guzzle as a dependency
php composer.phar require guzzle/iterator:~3.0

After installing, you need to require Composer's autoloader:

require 'vendor/autoload.php';
