Solar_Cache_Adapter_Var::entry()

public mixed Solar_Cache_Adapter_Var::entry ( string $key )

Returns the adapter-specific name for the entry key.

Inherited from Solar_Cache_Adapter.

Parameters

  • (string) $key: The entry ID.

Returns

  • (mixed) The adapter-specific name for the entry key.

Description

Returns the adapter-specific name for the entry key.

Cache adapters do not always use the identifier you specify for cache entries. For example, the [Solar_Cache_Adapter_File:HomePage file adapter] names the cache entries based on an MD5 hash of the entry ID. This method tells you what the adapter is using as the name for the cache entry.

<?php
// create a request object
$request = Solar_Registry::get('request');

// create an entry ID named for the current URI
$id = $request->server('REQUEST_URI');

// create a cache object
$cache = Solar::factory('Solar_Cache');

// find out what the underlying cache adapter uses as the entry name
$real_name = $cache->entry($id);
