Pádraic Brady, looking ahead to the work he will be doing over the next few months, is proposing on his blog about a new Zend Framework component - Zend_Service_Currency.

I did a quick check on what PHP classes are available for the purpose. There's really not a whole lot out there. There's a PEAR class along the lines I need, but it's released under the PHP License and, not to be too argumentative, I prefer non-PEAR solutions where the end-user may have no access to update PEAR.

So since the project is planned to use the Zend Framework, I shot off a mail to the Framework's fw-general mailing list to see if it would be a worthwhile contribution.

He sees that someone else had already opened a proposal for the same idea and decided to join with that group to work up the module. He also links to his original proposal and gives a brief overview of the goals of the package.
