Hello. This is a PHP5 benchmarking class.

WHY?
====
Often there are two or more ways to do the same thing. Sometimes they
both are nice to write. The key criterion is now: performance. But
how to test the performance of an PHP code? I'm tired of writing a loop
for many executations and using microtime(true).

So I've written a class which is able to do this.

HOW?
====
This class supports two ways of performance comparison:
    - The class calls a given function e.g. 10'000 times and clocks the
      time needed.
    - The class calls a given function permanently until X seconds
      running time reached and counts the number of started calls.
      
In benchmarks/example.php you can find an working example, which
compares the „switch“ structure and the „?:“ operator using both
methods.
Output may be something like that:

		:php-benchmark/benchmarks$ php example.php
		Benchmark by time...
		+-------------+--------+------------+
		| Name        | Count  | Percentage |
		+-------------+--------+------------+
		| ?: operator | 395106 | 100%       |
		| switch(){}  | 427235 | 108%       |
		+-------------+--------+------------+
		Benchmark by calls...
		+-------------+---------------+------------+
		| Name        | Time          | Percentage |
		+-------------+---------------+------------+
		| switch(){}  | 2.60735988617 | 100%       |
		| ?: operator | 3.03899979591 | 117%       |
		+-------------+---------------+------------+

NOTE
====
In the context of this class 'performance' is meaned referring to time.
The class does NOT detect CPU load, RAM usage or such things.

Can I help you?
===============
Of course! I'm sure the files contain programming errors and lots of
English language mistakes. Find them and send them to me ;-)
