设置一个每日cron作业来完成所有的后期检查竞价怎么样？

// function for activation hook
function expire_posts() {
    // check if scheduled hook exists
    if ( !wp_next_scheduled( \'post_expire_event\' )) {
         // Schedules a hook
         wp_schedule_event( time(), \'daily\', \'post_expire_event\' );
    }
}

add_action( \'post_expire_event\', \'post_expiration_check\' );

function post_expiration_check() {
   $posts = get_posts([
        \'post_status\' => \'publish\'
   ]);

   if(date(\'D\', $timestamp) === \'Mon\') {
       if(!empty($posts)) {
            foreach($posts as $post) {
                wp_update_post([ \'ID\' => $post->ID, \'post_status\' => \'draft\' ]);
            }
       }
   }  
}
