Timer basic usage

  1. Start benchmark by execute \Benchmark\Performance\Timer::start(), that will launch time storage.
  2. To measure time from start time, until some position use ::setMarker('some description'), that will save time execution and memory usage from start, or previous marker to current position.
  3. After we set sime markers, use ::stop() to halt benchmark.
  4. Use ::calculateStats() to get information about execution time and memory usage.
\Benchmark\Performance\Timer::start();

sleep 3;

\Benchmark\Performance\Timer::setMarker('sleep');

sleep 5;

\Benchmark\Performance\Timer::setMarker('another sleep');

\Benchmark\Performance\Timer::stop();
var_dump(\Benchmark\Performance\Timer::calculateStats());
  1. If you want to get formatted output, look down for Timer formatting output section.

Timer advanced usage

For more cleared view, we can join stats into groups, to see, how mutch time and memory use whole group. To begin measure in group use ::startGroup('group name'), set markers inside and use ::endGroup('group name') with the same name to store stats inside one group. Of course there is possibility to create nested groups.

Timer other functions

  • start() can have additional boolean argument, if false, then will whole timer will be disabled
  • turnOffBenchmark() allow to turn off Timer
  • turnOnBenchmark() allow to turn on Timer

Timer formatting output

There are three possibilities to get formatted output. First one allow to ger output as array with formatted time, memory and percentage values. second one allow to get output formatted by Symfony Console output class. And last one allow to get output as HTML.

Pre-formatted array

After \Benchmark\Performance\Timer::stop(); execute (Timer::getFormattedOutput('raw+') to get array with formatted memory, time and percentage. Using raw as parameter return raw values, the same as usage of \Benchmark\Performance\Timer::calculateStats();

Console output

After \Benchmark\Performance\Timer::stop(); execute (Timer::getFormattedOutput('shell') to get formatted output for console. Output will be equivalent of that:

Total application runtime: ~1 001.8280 ms    Total memory usage: ~3602 kB
=========================================================================

val: 0 ~0.0050 ms    0.00050 %    ~0,000 kB
val: 1 ~100.1649 ms    9.99821 %    ~0,000 kB
val: 2 ~100.1842 ms    10.00014 %    ~0,000 kB
val: 3 ~100.1740 ms    9.99912 %    ~0,000 kB
val: 4 ~100.1639 ms    9.99812 %    ~0,000 kB
    example group START
    val: 0 ~100.2018 ms    10.00190 %    ~0,000 kB
    val: 1 ~100.1649 ms    9.99821 %    ~0,000 kB
    val: 2 ~100.1790 ms    9.99962 %    ~0,000 kB
    val: 3 ~100.1539 ms    9.99712 %    ~0,000 kB
    val: 4 ~100.1499 ms    9.99671 %    ~0,000 kB
    example group END

HTML output

After \Benchmark\Performance\Timer::stop(); execute (Timer::getFormattedOutput('html') to get formatted output for browser. Output will be equivalent of that:

<div style="
    color: #fff;
    background-color: #000;
    border: 1px solid #fff;
    width: 90%;
    text-align: center;
    margin: 25px auto;
">
    Total application runtime: ~1 001.8280 ms&nbsp;&nbsp;&nbsp;&nbsp;Total memory usage: ~3129.140625 kB
    <br />
    <br />
    Marker times:
    <br />
    <table style="width:100%">
        <tr style="background-color:#202020">
            <td style="width:40%;color:#fff">val: 0</td>
            <td style="width:20%;color: #fff;">~0.0050 ms</td>
            <td style="width:20%;color: #fff;">0.00050 %</td>
            <td style="width:20%;color:#fff">~0,000 kB</td>
        </tr>

Write own output formatter

If you want to get data in you own specified format, you can apply it to method calculateStats. This method accept callable type to process data array before it will be returned.
This is how it looks inside the original code: self::calculateStats([Formatter::class, 'formatValues']); - this will execute method formatValues from Formatter::class class.

Screenshots

Install via Composer

To use packages you can just download package and pace it in your code. But recommended way to use ClassBenchmark is install it via Composer. To include ClassBenchmark libraries paste into composer json:

{
    "require": {
        "chajr/class-benchmark": "version"
    }
}

Required for ClassBenchmark libraries (ClassKernel) will be loaded automatically.
