Installation

Add this in your composer.json

{
    "require": {
        "ggomuk/g-bench": "1.0.0"
    }
}

Sample Usage

• start(), stop()

  require_once __DIR__ . '/vendor/autoload.php';
  
  $gb = new \GBench\GBench();
  
  $gb->start();
  $temp = str_repeat('Hello World!', 10000);
  sleep(2);
  $gb->stop();
  
  $gb->getDuration(); // 2003 (ms)
  $gb->getMemory(); // 2097152 (bytes)
  
  echo $gb; // 2.00 MB - 2003 ms

• record()

  require_once __DIR__ . '/vendor/autoload.php';
  
  $gb = new \GBench\GBench();
  
  $gb->start();
  
  usleep(500000);
  $temp1 = str_repeat('Hello World!', 10000);
  
  // You can label records with the record method.
  // The benchmark does not stop as it only makes an intermediate record.
  $gb->record('step1');
  
  usleep(500000);
  $temp2 = str_repeat('Hello World!', 100000);
  
  // You can also label records with the stop method.
  $gb->stop('step2');
  
  // The details of the record can be seen below
  foreach ($gb->getRecords() as $record) {
      $record->getLabel(); // step1, step2
      $record->getMemory(); // 2097152, 2097152
      $record->getDuration(); // 505, 506
      $record->getAccumulateMemory(); // 2097152, 4194304
  
      echo $record;
      // Usage Memory : 2.00 MB | Accumulate Usage Memory : 2.00 MB | Record Duration : 505 ms -> step1
      // Usage Memory : 2.00 MB | Accumulate Usage Memory : 4.00 MB | Record Duration : 506 ms -> step2
  }

• run()

  require_once __DIR__ . '/vendor/autoload.php';
  
  $gb = new \GBench\GBench();
  $result = $gb->run(function () {
      usleep(500000);
      return str_repeat('Hello World!', 10000);
  }, 'sample_run');
  
  $gb->getDuration() . "\n"; // 504 (ms)
  $gb->getMemory() . "\n"; // 2097152 (bytes)
  echo $gb . "\n"; // 2.00 MB - 504 ms

• Handler

  require_once __DIR__ . '/vendor/autoload.php';
  
  $logger = new class extends \GBench\AbstractHandler {
      public function startAfter(\GBench\GBench $gbench)
      {
          echo 'good start';
      }
  
      public function stopAfter(\GBench\GBench $gbench, \GBench\Record $record)
      {
          echo 'good stop';
      }
  };
  
  $gb = new \GBench\GBench($logger);
  $gb->start(); // good start
  $gb->stop(); // good stop
