Basic Usage - Psr16 Simple Cache

Psr16 is a standard for cache in PHP with less verbosity than Psr6.

You can just instantiate the cache engine and use it as you can see below.

Get an element from cache and set if not exists

<?php
$cacheEngine = new \ByJG\Cache\Psr16\FileSystemCacheEngine();

$result = $cacheEngine->get($key);
if (empty($result))
{
    // Do the operations will be cached
    // ....
    // And set variable result
    $result = "...";

    // Set the cache:
    $cacheEngine->set($key, $result, 60);
}
return $result;

Check if an element exists in cache

<?php
$cacheEngine = new \ByJG\Cache\Psr16\FileSystemCacheEngine();
if ($cacheEngine->has($key)) {
    // ...
}

Delete an element from cache

<?php
$cacheEngine = new \ByJG\Cache\Psr16\FileSystemCacheEngine();
$cacheEngine->delete($key);

Clear all cache

<?php
$cacheEngine = new \ByJG\Cache\Psr16\FileSystemCacheEngine();
$cacheEngine->clear();
