A simple file cache for PHP

Installation

composer require arkonsoft/ps-file-cache

Usage

Create a new instance of the cache:

use Arkonsoft\PsModule\FileCache;
...
$cache = new FileCache(__DIR__ . '/cache/');

Store a value in the cache:

$cache->store('key', 'value');

Get a value from the cache:

$value = $cache->retrieve('key');

Retrieve method will also check whether the key is expired or not. You can turn off this feature by passing false as the second argument:

$value = $cache->retrieve('key', false);

Important

store() method uses json_encode() to serialize data. You can store any data beside "resource" type. If you'll try to do it exception will be thrown.

Additional methods

Lifetime

Base lifetime is set to 3600 seconds (1h).

You can change it in the constructor:

$cache = new FileCache('path', 6000);

Or later with:

$cache->setLifetime(6000);

IsStored

Check if a key is stored in the cache and is not empty:

$cache->isStored('key');

IsExpired

Check if a key is stored in the cache and is expired:

$cache->isExpired('key');
