Description:
------------
For temporary files rather than generic data, I'm using this to manage temporary file uploads, a common example would be file attachments for a webmail program. This saves needed an external crontab to clean up old files.

<?php

/**
* This class extends Cache_Lite for use with temporary files.
*
* @package Cache_Lite
* @version $Id$
* @author Steven McCoy <fnjordy@gmail.com>
*/

require_once('Cache/Lite.php');
class Cache_Lite_Temp extends Cache_Lite
{

// --- Public methods ---

/**
* Constructor
*
* $options is an assoc. To have a look at availables options,
* see the constructor of the Cache_Lite class in 'Cache_Lite.php'
*
* @param array $options options
* @access public
*/
function Cache_Lite_Temp($options)
{
$this->Cache_Lite($options);
}

/**
* Move a file into the cache (c.f. save)
*/
function save($file_name, $id, $group = 'default')
{
if ($this->_caching) {
if (isset($id)) {
$this->_setFileName($id, $group);
}
if ($this->_automaticCleaningFactor>0) {
$rand = rand(1, $this->_automaticCleaningFactor);
if ($rand==1) {
$this->clean(false, 'old');
}
}
return rename($file_name, $this->_file);
}
return false;
}

/**
* Check for id in cache but do not return it (c.f. get)
*/
function exists($id, $group = 'default', $doNotTestCacheValidity = false)
{
$this->_id = $id;
$this->_group = $group;
if ($this->_caching) {
$this->_setFileName($id, $group);
if ($doNotTestCacheValidity) {
if (file_exists($this->_file)) {
return true;
}
} else {
if ((file_exists($this->_file)) && (@filemtime($this->_file) > $this->_refreshTime)) {
return true;
}
}
}
return false;
}

}
?>

Test script:
---------------
None atm.

I'm sorry but I think it's too specific for an integration into Cache_Lite
