README

PHP performance comparing measuring class.

To generate a benchmark report:

$p = new perf(100000);  # each test 100000 times

$p->test('strrpos()', function () {
   if(strrpos($string, ':'));
);

echo $p->report();  # output result

or step by step:

$p = new perf();
$p->start();
for($i=100000;$i;$i--) { -- checking performance of strrpos
    if(strrpos($string, ':'));
}
$p->stop('strrpos()');
$p->report();

->test('label', function(){})

short for ->start(), any code, ->stop()

->start()

init a new time measuring

->stop('label')

stop measuring and set label for it

->report()

generates the output

Output sample:

100.0% 0.37274s str_contains()
104.6% 0.38981s strpos(+pos)
105.1% 0.39162s strrpos(+pos)
108.7% 0.40509s strrpos()
112.6% 0.41980s [x]===':'
120.4% 0.44880s strpos()
143.9% 0.53623s substr_compare()
247.6% 0.92283s preg_match

If the the results are too far apart and the runtime is very smal/fast, incrase itterations. The first entry (100%) is the benchmark, so each other test is measured to this.
