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.
