Currency Rate Scraper

An ugly, but yet useful PHP port of the Open Exchange Rates project, intended for hosted/cronjob use.

How to use?

In your terminal:

git clone git://github.com/tzvetkoff/currency-rate-scraper
cd currency-rate-scraper
./scraper.php
ls

If you see a latest.json file then everything is OK. You should probably want to schedule the script to execute automatically in the background, so, again in your terminal:

crontab -e

This should open you a text editor with some cryptic lines - if you don't know what they mean, read the fine manual here. I usually schedule the script every 15 minutes:

*/15 * * * * /path/to/currency-rate-scraper/scraper.php >/dev/null 2>&1

Other than that, you can keep history of the rates in the ./historical/ directory, configure the script to automatically commit the changes in a git repository, and further push the changes to a remote host (such as GitHub, although it's not recommended - the idea behind is to use and modify the script for your own needs, thus host currency rates by yourself), but if you know what git is, you should not need any further explanations - just hack the code.
