DevShed has posted the second article in their series looking at benchmarking your PHP scripts. This time they look at the use of “timers” to check on script execution length.
Since you already know how to create timer functions and classes, in this tutorial, I’ll create some concrete examples that show where these timing mechanisms can be applied in order to evaluate the performance of certain PHP applications.
They create a few classes that connect to a database and pull out rows (handing it off to a Result class). They use these classes in two examples – one with compression (output buffering) and one without using their Timer class to evaluate the differences.
