Sometimes it is necessary to invest some effort in optimizing applications that make significant use of hardware resources to reduce the costs of maintaining the sites where the applications are hosted.

When the applications are large it is not always easy to tell what exactly needs to be optimized. The solution consists on finding the which parts of the application consume most of the time to execute. This is the goal of application profiling tools.

This class provide a solution for profiling PHP scripts. It uses the ticks callback handler functions to locate which parts of the application are executing and how long it is taking to finish.

With this information it can produce reports that can give the developer a better idea of which are the expensive parts of their application that may be more worth investing optimization effort.
