[TYPO3] clear cache from cron script

[Loek Hilgersom]

Hi Dimitry,

Thanks for your suggestion, I got it to work!

Here's the entire script, for whoever is interested in clearing the Typo3 cache 
from applications outside of Typo3. The way it's set up now the script should be 
located in typo3conf/ext/your_extension/scriptname.php, otherwise you'll have to 
adjust the path definitions on top.

Cheers,
Loek


<?php

define("PATH_typo3conf", dirname(dirname(dirname(__FILE__)))."/");
define("PATH_site", dirname(PATH_typo3conf)."/");
define("PATH_typo3", PATH_site."typo3/");       // Typo-configuraton path
define("PATH_t3lib", PATH_site."t3lib/");
define('TYPO3_MODE','BE');
ini_set('error_reporting', E_ALL ^ E_NOTICE);

require_once (PATH_t3lib.'class.t3lib_div.php');
require_once (PATH_t3lib.'class.t3lib_extmgm.php');
require_once (PATH_t3lib.'class.t3lib_tcemain.php');

require_once(PATH_t3lib.'config_default.php');

if (!defined ("TYPO3_db")) die ("The configuration file was not included.");
require_once(PATH_t3lib.'class.t3lib_db.php');          // The database library
$TYPO3_DB = t3lib_div::makeInstance('t3lib_db');
$TYPO3_DB->sql_pconnect (TYPO3_db_host, TYPO3_db_username, TYPO3_db_password);
$TYPO3_DB->sql_select_db (TYPO3_db);

$tce = t3lib_div::makeInstance('t3lib_TCEmain');
$tce->clear_cacheCmd(40);  // ID of the page for which to clear the cache

?>
