PHPQuickProfiler a small tool (think Firebug for PHP) to provide profiling and debugging related information to developers without needing them to add a lot of programmatic overhead to their code. Now, we only need to toggle one config setting to true and you have access to an automated tool to help create a faster and more consistent code review experience.
You can find the original documentation here.
The PHPQuickProfiler vendor package is used by FuelPHP in the Profiler class, to display profiling output when the profiler is enabled.
You can add data to PHPQuickProfiler through the Profiler class methods.
