Class Phalcon\Cache\Backend\File¶extends abstract class Phalcon\Cache\Backend implements Phalcon\Cache\BackendInterface Allows to cache output fragments using a file backend <?php
//Cache the file for 2 days
$frontendOptions = array(
'lifetime' => 172800
);
//Create a output cache
$frontCache = \Phalcon\Cache\Frontend\Output($frontOptions);
//Set the cache directory
$backendOptions = array(
'cacheDir' => '../app/cache/'
);
//Create the File backend
$cache = new \Phalcon\Cache\Backend\File($frontCache, $backendOptions);
$content = $cache->start('my-cache');
if ($content === null) {
echo '<h1>', time(), '</h1>';
$cache->save();
} else {
echo $content;
}
Methods¶public __construct (unknown $frontend, [unknown $options]) Phalcon\Cache\Backend\File constructor public mixed get (unknown $keyName, [unknown $lifetime]) Returns a cached content public save ([unknown $keyName], [unknown $content], [unknown $lifetime], [unknown $stopBuffer]) Stores cached content into the file backend and stops the frontend public boolean delete (unknown $keyName) Deletes a value from the cache by its key public array queryKeys ([unknown $prefix]) Query the existing cached keys public boolean exists ([unknown $keyName], [unknown $lifetime]) Checks if cache exists and it isn’t expired public mixed increment ([unknown $keyName], [unknown $value]) Increment of a given key, by number $value public mixed decrement ([unknown $keyName], [unknown $value]) Decrement of a given key, by number $value public boolean flush () Immediately invalidates all existing items. public string getKey (unknown $key) Return a file-system safe identifier for a given key public this useSafeKey (unknown $useSafeKey) Set whether to use the safekey or not public getFrontend () inherited from Phalcon\Cache\Backend ... public setFrontend (unknown $frontend) inherited from Phalcon\Cache\Backend ... public getOptions () inherited from Phalcon\Cache\Backend ... public setOptions (unknown $options) inherited from Phalcon\Cache\Backend ... public getLastKey () inherited from Phalcon\Cache\Backend ... public setLastKey (unknown $lastKey) inherited from Phalcon\Cache\Backend ... public mixed start (unknown $keyName, [unknown $lifetime]) inherited from Phalcon\Cache\Backend Starts a cache. The keyname allows to identify the created fragment public stop ([unknown $stopBuffer]) inherited from Phalcon\Cache\Backend Stops the frontend without store any cached content public boolean isFresh () inherited from Phalcon\Cache\Backend Checks whether the last cache is fresh or cached public boolean isStarted () inherited from Phalcon\Cache\Backend Checks whether the cache has starting buffering or not public int getLifetime () inherited from Phalcon\Cache\Backend Gets the last lifetime set |
