Simple PHP Profiler

This is the tool to profile any code you have.

This initial version contains only time profiling for now.

Example

This simple example demonstrates basic usage of profiler.

<?php
    require_once 'Profiler.php';

    class ToProfile {
    
        protected $profiler;


        public function __construct() {
            $this->profiler = new Profiler( './toProfile' );                
        }


        public function methodToProfile() {
            $profilingSession = $this->profiler->start( 'methodToProfile' );

            sleep(1);

            $profilingSession->step( 'Before some long playing code...' );

            sleep(3);

            $profilingSession->step( 'After some long playing code...' );

            sleep(1);

            $profilingSession->stop();

        }
    }

    $toProfile = new ToProfile();
    
    $toProfile->methodToProfile();

?>

This code will generate ./toProfile/methodToProfile.log file with following content:
