Benchmark_Iterate

About Benchmark_Iterate

This class is useful when you want to iterate over a single piece of code (a function) several times over. Timing information is recorded for every iteration. An example follows.

<?php

require_once 'Benchmark/Iterate.php';

$benchmark = new Benchmark_Iterate;

function calculation($num) {
    $x = sin($num) * 100;
    $y = tan($x);
    return;    
}

$benchmark->run(100, 'calculation', 45.6);
$result = $benchmark->get();
print_r($result);

?>

The example above will generate an output as shown below when run with the PHP CLI SAPI.

Array
(
    [1] => 0.000073
    [2] => 0.000014
    [3] => 0.000011
    [4] => 0.000011
    [5] => 0.000011
	..93 more results..
	[99] => 0.000011
    [100] => 0.000011
    [mean] => 0.000011
    [iterations] => 100
)

You can display formatted results either by running the script in automatic mode or by using the display() method. For more information of the methods this class implements, refer to the API documentation.
