Cacher

A simple, general-purpose, file-based cache provider

Basic usage

First require biohzrdmx/cacher-php with Composer.

Now create a Cacher instance passing the cache directory and optionally, the caching time:

$cacher = new Cacher(dirname(__FILE__) . '/cache');

Once you've created the instance you may start manipulating the cache items, for example, by adding a new item:

$cacher->store('results', $results);

The next time you need to use the results data, just recover them from the cache. The first thing to do is check if it exists and if it's still fresh:

$cacher->isCached('results');

The isCached method will return true if the data is in the cache and is fresh enough. Once you've checked it, recover its contents:

$results = $cacher->retrieve('results');

And that's it. Easy peasy.

Usually all those operations are executed in the following form:

use Cacher\Cacher;

$cacher = new Cacher(BASE_DIR . '/cache');

if ( $cacher->isCached('results') ) {
  $results = $cacher->retrieve('results');
} else {
  $results = fetchResultsFromSomeSource();
  $cacher->store('results', $results);
}

You may also specify a serialize and unserialize callback with the setSerializer($serializer) and setUnserializer($unserializer) methods.

Finally if you want to delete a cached item you may do so with the delete($name) function.
