FirePHP is a Firefox extension that enables you to print to your Firebug console using a simple PHP function call.
FirePHP is ideally suited for AJAX development where clean JSON or XML responses are required. All data is sent via a set of X-FirePHP-Data response headers. This means that the debugging data will not interfere with the content on your page.
You must have Firebug installed and the "Net" panel enabled to use this extension.
You must also download a PHP library from http://www.firephp.org/
