Hier nun meine Task-Datei.
Kann mich jemand über meine geistige Umnachtung aufklären?  

PHP-Code:

function task_sn_backupcleaner($task) {
    global $mybb, $lang, $config;
    $lang->load('sn_backupcleaner');

    if(!defined('MYBB_ADMIN_DIR'))
    {
        if(!isset($config['admin_dir']))
        {
            $config['admin_dir'] = "admin";
        }

        define('MYBB_ADMIN_DIR', MYBB_ROOT.$config['admin_dir']);
    }
    
    // Check if folder is writable
    if(!is_writable(MYBB_ADMIN_DIR."/backups"))
    {
        add_task_log($task, $lang->sn_backupcleaner_cantwrite);
    } 
             
        $ba_files = MYBB_ADMIN_DIR."/backups/*.sql.gz";
        $backup_file = glob($ba_files);
        $ba_count = 0;
        $ba_min = $mybb->settings['backupcleaner_keep'];
        $ba_age_max = $mybb->settings['backupcleaner_delay'];
    
    // delete every file in the array which is >= $ba_age_max days and keep files = $ba_min    
    if(count($backup_file) > $ba_min)
    {
        foreach($backup_file as $ba)
        {
        if(is_file($ba) && time() - filectime($ba) >= $ba_age_max*24*60*60)
        {
        $ba_count++;    
        unlink($ba);
        }
        }
        add_task_log($task, $lang->sprintf($lang->sn_backupcleaner_ran, $ba_count));
    }    
}
