So the amazing guys at Particletree built this awesome php profiler and I thought I would share my mods of integrating it into CI. My code is a bit of a hack job but you should get the idea. Start by checking out the Particletree blog post at http://particletree.com/features/php-quick-profiler/. Reading through that will give you an idea of what the profiler can accomplish and how to log to its console.

Install

1. Make sure that hooks are enabled in your application/config/config.php file.

2. Copy the files from the download to the corresponding directories in your
   application directory. Make sure you don't overwrite any of your own files
   if you've customized them. You may need to create the plugins directory
   under application.

   config => system/application/config
   libraries => system/application/libraries
   plugins => system/application/plugins

3. Once that's done, anywhere you enable the profiler using
   $this->output->enable_profiler(TRUE), you should see the new profiler

Notes

• The plugin is loading using hooks so it can be initialized before most of the
  CI system. You could autoload it instead, but you'd miss out on a lot of
  the CI loading process.

• It's not php4 compatible. If you use php4 still, think of this as a
  fantastic perk you get once you finally upgrade. Oh and upgrade from
  IE6 while you're at it too please ;)
