如何在没有Crontab的情况下每两周在PHP中调用一个方法

Question

I want to update the div in html to display different contents every week with just php and without the use of cron. How will it be posssible to achieve it ? The following code is for activating the code every 2 month on the 10nth day but I guess the logic will be different. If possible some hint or example will be great ! I will love to hear from you!

    // 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 */

    }
}

I've just updated your example, now it will work every next Monday:

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