Stopwatch – Class for checking delays during code execution

Why you might need this

If you don’t want to use complex tools for code profiling, but just need to find a place that slows down the execution of all code.

Installation & loading

Just add this line to your composer.json file:

"alex-heifetz/stopwatch": "^1.0"

or run

composer require seraph90/stopwatch

A Simple Example

<?php

// Import Stopwatch class into the global namespace
use Heifetz\Stopwatch;

// Load Composer's autoloader
require 'vendor/autoload.php';

// Create an instance;
// We can set a threshold that doesn't interest us
$stopwatch = new Stopwatch(210000);

usleep(500000);
// Add first time measurement
$stopwatch->add('500000');

usleep(200000);
// Add another, this one must be skipped by threshold
$stopwatch->add('200000');

usleep(300000);
$stopwatch->add('300000');

// Display all timings 
print_r($stopwatch->getTimings());
// Result like:
//
// Array
// (
//     [500000] => 0.505021
//     [300000] => 0.300916
// )
//
