README

Windwalker Profiler can help us profiler some process information for debug.

Installation via Composer

Add this to the require block in your composer.json.

{
    "require": {
        "windwalker/profiler": "~3.0"
    }
}

Create A Profiler And Mark A Point

use Windwalker\Profiler\Profiler;

$profiler = new Profiler;

$profiler->mark('StartRender');

// Execute some code...

$profiler->mark('AfterRender');

// Execute some code...

$profiler->mark('End');

Now your can get the elapsed time between two points:

$profiler->getTimeBetween('StartRender', 'AfterRender');

Or get memory amount between two points:

// Return memory bytes
$profiler->getMemoryBetween('StartRender', 'AfterRender');

Output Result

echo $profiler->render();
Notes 0.000 seconds (+0.000); 0.00 MB (+0.000) - StartRender
Notes 1.000 seconds (+1.000); 3.00 MB (+3.000) - AfterRender
Notes 1.813 seconds (+0.813); 6.24 MB (+3.240) - End

Benchmark

Benchmark is a convenience object to test two or more tasks executing time.

use Windwalker\Profiler\Banchmark;

$benchmark = new Benchmark;

$benchmark->addTask('task1', function()
{
    md5(uniqid());
})
->addTask('task2', function()
{
    sha1(uniqid());
});

$benchmark->execute(10000);

echo $benchmark->render();

The output

task1 => 0.204897 s
task2 => 0.205108 s

Use Other format

$benchmark->setTimeFormat(Benchmark::MILLI_SECOND)->execute(10000);

echo $benchmark->render();

/* Result
task1 => 187.489986 ms
task2 => 207.049847 ms
*/
$benchmark->setTimeFormat(Benchmark::MICRO_SECOND)->execute(10000);

echo $benchmark->render();

/* Result
task1 => 198050.9758 μs
task2 => 206343.173981 μs
*/

Custom Render Handler

$benchmark->setRenderOneHandler(function($name, $result, $round, $format)
{
    return $name . ' : ' . round($result, $round);
});

$benchmark->render();
