pench

Another PHP benchmark system

This library benchmark php applications and show time_elapsed,memory_usage and memory_peak_usage, but you should consider there is no way to get precise amount of memory consumed by the application because there is no way for php to report it, the memory_get_usage(false) just report the memory that is allocated not actually using by the application but it's near the real memory usage by the application.
, _(*1)

Install pench via composer, _(*2)

composer require hosseinmousavi/pench:dev-master

Then include composer autoload file, _(*3)

require 'vendor/autoload.php';

Or just include it, _(*4)

require 'src/pench.php';

pench API is damn simple, see example below, _(*5)

require 'pench.php';
$haystack = rang(1,1000000);

pench::start();
foreach($haystack as $value) {
  echo $value;
}
$report['foreach']=pench::end();
var_dump($report);

Will output, _(*6)

array (size=1)
  'foreach' => 
    array (size=3)
      'time_elapsed' => string '24.709722042084 Sec' (length=19)
      'memory_usage' => string '112 Byte' (length=8)
      'peak_memory_usage' => string '176 Byte' (length=8)

Also you can use dump() to print the report and it's not necessary to call end() because dump itself will call it, it's possible to pass a label to dump() so it'll be clear which result belongs to what part of the program., _(*7)

require 'pench.php';

pench::start();

$haystack = rang(1,1000000);

array_walk($haystack,function($value){

  echo $value;

});

pench::dump('array_walk');

will ouput, _(*8)

array (size=1)
  'array_walk' => 
    array (size=3)
      'time_elapsed' => string '0.11225986480713 Sec' (length=20)
      'memory_usage' => string '152 Byte' (length=8)
      'peak_memory_usage' => string '176 Byte' (length=8)

For benchmarking multiple parts you should call pench::start() every time., _(*9)

pench::start();

foreach($haystack as $value) {

  echo $value;

}

$report['foreach']=pench::end();//or pench::dump('array_foreach') or pench::dump() to print report inline

pench::start();

array_walk($haystack,function($value){

  echo $value;

});

$report['array_walk']=pench::end();//or pench::dump('array_walk') to print report inline

use benchmark() to fetch last report, _(*10)

pench::start();

foreach($haystack as $value) {

  echo $value;

}

pench::end();//or pench::dump('array_foreach') or pench::dump() to print report inline

var_dump(pench::benchmark());
