推荐答案

您可以创建一个使用strtotime（）递归计算天数的函数。由于 strtotime（next monday）; 工作正常。

You could create a function that uses strtotime() recursively to count the number of days. Since strtotime("next monday"); works just fine.

function daycount($day, $startdate, $counter)
{
    if($startdate >= time())
    {
        return $counter;
    }
    else
    {
        return daycount($day, strtotime("next ".$day, $startdate), ++$counter);
    }
}

echo daycount("monday", strtotime("01.01.2009"), 0);

希望这是您要找的东西：）
