Measure the passing of time -- by, Chris Kankiewicz (@PHLAK), logo by Caneco

Introduction

Chronometer is a library for statically measuring the passing of time in your code. It's intended to be used for benchmarking code execution time.

Requirements

• PHP >= 7.1

Install with Composer

composer require phlak/chronometer

Using Chronometer

First, import Chronometer.

use PHLAK\Chronometer\Timer;

Then start your timer, run your code, stop the timer and get the elapsed time.

Timer::start();
// do something you want to measure...
Timer::stop();

return Timer::elapsed();

After running your timer you will need to reset it before using it again.

Timer::reset();

You may optionally reset the timer when you start it with the $reset parameter.

Timer::start($reset = true);

Usage

start

Start the timer.

Chronometer\Timer::start( [ $reset = false ] ) : float

Example

Chronometer\Timer::start(); // Returns something like 1538016612.1692

---

stop

Stop the timer.

Chronometer\Timer::stop( void ) : float

Example

Chronometer\Timer::stop(); // Returns something like 1538016632.7721

---

addLap

Add a new lap.

Chronometer\Timer::addLap( [ string $description = null ] ) : Chronometer\Lap

Example

$lap = Chronometer\Timer::addLap('The first lap.');

$lap->time // Returns something like 1538016625.492
$lap->duration // Returns something like 7.999922990799
$lap->description // Returns 'The first lap.'

---

started

Return the timer start time.

Chronometer\Timer::started( void ) : float

Example

Chronometer\Timer::started(); // Returns something like 1538016612.1692

---

stopped

Return the timer stop time.

Chronometer\Timer::stopped( void ) : float

Example

Chronometer\Timer::stopped(); // Returns something like 1538016632.7721

---

elapsed

Return the total time elapsed in seconds.

Chronometer\Timer::elapsed( void ) : float

Example

Chronometer\Timer::elapsed(); // Returns something like 20.602929115295

---

lastLap

Return the last lap.

Chronometer\Timer::lastLap( void ) : Chronometer\Lap

Example

$lap = Chronometer\Timer::lastLap();

$lap->time // Returns something like 1538016632.7721
$lap->duration // Returns something like 7.2800490856171

---

laps

Return an array of all laps.

Chronometer\Timer::laps( void ) : array

Example

Chronometer\Timer::laps(); // Returns an array of Lap objects

---

reset

Reset the timer state.

Chronometer\Timer::reset( void ) : void

Example

Chronometer\Timer::reset();
