---



A [PHP][1] library that provides a high-performance caching system for storing the results of expensive computations, database queries, or network requests. Supports both [PSR-6][2] and [PSR-16][3] caching standards.



## 📦 Installation



This project requires [PHP][1] 7.2 or higher. The recommended way to install, is via [Composer][4]. Simply run:



```bash

$ composer require biurad/cache

```



## 📍 Quick Start



One of the key features of this library is its ability to cache the result of a callable or function, allowing for the caching of complex computations or database queries. Additionally, it includes a fallback load feature to ensure that the cached value is always fetched, even if it has expired from the cache.



Here is an example of how to use the library using [symfony/cache][5]:



```php

use Biurad\Cache\FastCache as Cache;

use Psr\Cache\CacheItemInterface;

use Symfony\Component\Cache\Adapter\PhpFilesAdapter;



$storage = new PhpFilesAdapter(directory: __DIR__.'/cache');

$cache = new Cache($storage);

$cache->setCacheItem(\Symfony\Component\Cache\CacheItem::class);



// The callable will only be executed on a cache miss.

$value = $cache->load(

    'my_cache_key',

    static function (CacheItemInterface $item): CacheItemInterface {

        $item->expiresAfter(3600);



        // ... do some HTTP request or heavy computations

        $item->set('foobar');



        return $item;

    }

);



echo $value; // 'foobar'



// ... and to remove the cache key

$cache->delete('my_cache_key');



// cache the result of the function

$ip = $cache->call('gethostbyaddr', "127.0.0.1");



function calculate(array $a, array $b): array {

    $result = [];

    foreach ($a as $i => $v) foreach ($v as $k => $m) $result[$i][$k] = $m + $b[$i][$k];



    return $result;

}



$matrix = $cache->wrap('calculate');

$result = $matrix([[1, 2, 3], [4, 5, 6]], [[7, 8, 9], [10, 11, 12]]) // [[8, 10, 12], [14, 16, 18]]



// Caching the result of printable contents using PHP echo.

if ($block = $cache->start($key)) {

	  ... printing some data ...



	  $block->end(); // save the output to the cache

}

```



> **NB:** The beta parameter found on cache methods default value is 1.0 and higher values mean earlier recompute. Set it to 0 to disable early recompute and set it to INF to force an immediate recompute:
