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.
