HTTP Class for PHP (supports both cURL and fsockopen)
20/01/2008Feb 2009: A couple bugs have been fixed and library updated.
This is a wrapper HTTP class that uses either cURL or fsockopen to harvest resources from the web. It supports a handy subset of functionalists of HTTP that are mostly needed in day to day coding. Scripts who need to communicate with other servers will find it useful. If you’re looking to invoke any RESTful API and don’t want to bother adding a bunch of libraries for that simple thing, just put this class and you’re set.
