...To makes things easy, the StandardDebugBar has all the built-in collectors activated. The DebugBar uses DataCollectors to collect data from your PHP code. Some of them are automated but others are manual. Use the DebugBar like an array where keys are the collector names. Includes generic data collectors and collectors for well-known libraries. Easily create your own collectors and their associated view in the bar. DebugBar is very easy to use and you can add it to any of your projects in no time.
