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.
Benchmark_Iterate in manual mode
<?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.
Results of a test run of Benchmark_Iterate
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.
