我想更新htML中的div,每周只用PHP显示不同的内容,而不使用cron.
如何实现它？以下代码用于在第10天每2个月激活一次代码
但我猜逻辑会有所不同.如果可能的话,一些提示或示例将是伟大的！我很乐意听到你的消息！

// check if current day is 10th and month is an even number
if (date('d')==10 && date('m') % 2 == 0) {
    // get todays-date (format: yyyymmdd)
    $today = date('Ymd'); 
    // get info about last run
    $last_run = VARiable_get('my_last_run',0);
    // check last run was not today
    if ($last_run!=$today) {
        // set last run to today
        variable_set('my_last_run',$today);

        /* Place your code here */

    }
}

$weekInYearNumber = (int)date('W');
$weekDayNumber = (int)date('w');
if ($weekDayNumber === 1 && $weekInYearNumber % 2 == 0) {
    // Rest of your code.
}
