README

I've got a handful of scripts that function as notifiers. They run on a schedule and consume RSS feeds or API endpoints or scrape web pages. Then they compare the data retrieved with what was last retrieved and notify me of any changes.

To do that, they need a way of caching whatever "last retrieved" was. This is a simple helper class for doing that. It works for string data and anything that can be JSON encoded/decoded or serialized/unserialized.

Usage

use cjrasmussen\DataCacheHandler\DataCacheHandler;

$dataCacheHelper = new DataCacheHandler('/home/cjrasmussen/scripts/.cache/');

$dataCacheHelper->initialize(__FILE__);

$cache = $dataCache->readSerialized();

$cache[] = 'Some new item to cache';

$dataCacheHelper->writeSerialized();

Installation
