21,158 users

FirePHP enables you to log to your Firebug Console using a simple PHP method call.

Not using Firebug 1.9+ on Firefox 8+? See http://firephp.org/
Collector's Note This is a tool for everyone who doesn't want to use one of the PHP debuggers, but wants more comfort than echo() gives you. You just include a .php-file and can output anything to a log-console with a simple fb($var, 'Label'). There are also a lot of advanced options like redirecting Exceptions or group logging-messages. It saves a great amount of time and eliminates the need of debug-divs in your homepages.
