PHPench

[![A pretty graph](graph.gif)](graph.gif)

PHPench creates a graphical output for a PHP benchmark. Plot the runtime of any function in realtime with GnuPlot and create an image out of the result.

Why is it useful?
-----------------

[](#why-is-it-useful)

#### Algorithms are beautiful

[](#algorithms-are-beautiful)

Sometimes the difference between two algorithms is hard to explain but easy to show.
For instance, take two sorting algorithms which both have a best-case runtime of `O(n*log n)`. Depending on the input, one can be much faster than the other. This tools helps you see what's going on.

#### Death to premature-optimizations

[](#death-to-premature-optimizations)

Whenever people tell you that using single quotes instead of double quotes around strings is a performance improvement, it's time to debunk some myths. Most of the time such programmer folklore turns out to be misguided and can actually be pretty harmful.
*"Premature emphasis on efficiency is a big mistake which may well be the source of most programming complexity and grief."* (Donald Knuth)
Let's be professionals. Let's measure.

Using PHPench feels a bit like writing a visual unit test. Check it out:
