README
phpcb (php code benchmark)
phpcb is a very simple and very lightweight tool for speed benchmarking of various little pieces of PHP code, written in PHP, of course.
Why
phpcb is meant to be used in those situations when there are multiple ways of how to do something - and you know all will have the exact same result - but you just can't decide which would ultimately be the best (meaning "fastest") to use.
Requirements
- PHP 7.4+
- BCMath Arbitrary Precision Mathematics library for PHP; shouldn't be a problem, since it is commonly shipped with PHP itself.
Installation
composer require --dev smuuf/-hpcb
Usage
Write your microbenchmarks in a some file. For example mymicrobench.php
(here placed in phpcb's root directory, so it's clear we rquire Composer's autoload file from correct place):
<?php require __DIR__ . '/../vendor/autoload.php'; $bench = new \Smuuf\Phpcb\PhpBenchmark; const COUNT = 100; $bench->addBench(function() { for ($i = 1; $i <= COUNT; $i++) {} }); $bench->addBench(function() { for ($i = COUNT; $i > 0; $i--) {} }); $bench->addBench(function() { for ($i = COUNT; $i--;) {} }); $bench->addBench(function() { for ($i = -COUNT; $i++;) {} }); $bench->run();
And then run it:
$ php ./mymicrobench.php
And observe results:
