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., _(*2)

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., _(*3)

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):, _(*4)

<?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:, _(*5)

$ php ./mymicrobench.php

And observe results:, _(*6)
