File cache implementation using PSR6

, _(*1)

PSR-6 Compilant File Cache

This is a basic PSR-6 implementation of cache using the filesystem, _(*2)

Installation

Install using composer, _(*3)

composer require overdesign/psr-cache

Usage

Basic example, _(*4)

<?php
use Overdesign\PsrCache\FileCacheDriver;

$cacheDir = __DIR__ . '/cache';

$cache = new FileCacheDriver($cacheDir);

$item = $cache->getItem('myItem');

if ($item->isHit()) {
    echo 'Item found in cache';
    var_dump($item->get());
} else {
    $item->set('my data');
    $item->expiresAfter(120); // Expire in 2 min

    $cache->save($item);
}

Garbage collector

The drivers only deletes expired files when you try to recover them explicitly., _(*5)

In order to clean the cache files you have three methods., _(*6)

clear() Deletes all the items in the current pool, _(*7)

clearExpired() Deletes all the expired items in the pool, _(*8)

gc() Acts as a garbage collector, _(*9)

It's not recommended to call the gc() method within the normal user flow operation as it can be a high time consuming operation. The ideal option is to set a cron to call the gc() method., _(*10)

You can pass various options to the method, see the phpdoc to know more about that options., _(*11)

TODO

• Add PSR-16 support
