# 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
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:
```bash
$ php ./mymicrobench.php
```
And observe results:
```php
