Question

此代码的作用：
它根据之前（$date）之前捕获的一天生成日期。它总是计数一个星期。例如。如果您的开始日期（$date）为07.04.2019，它将生成$final_amount次的日期。

因此，如果日期的开始是07.04.2019并且$final_amount是5，它将输出：

07.04.2019` (handled in separate code, as the first day is excluded in code!)
14.04.2019
21.04.2019
28.04.2019
05.04.2019

我的代码存在问题
，如果假日不适合，我需要跳过该日期。所以如果21.04.2019是假期，应跳过该假期，并在一周后以新日期替换。即使一个假期中有多个日期，它也应始终具有$final_amount的金额。我不知道如何实现此目标，因为我是PHP的新手。

setlocale(LC_TIME, "de_DE"); //only necessary if the locale isn't already set
$date = new DateTime(helper('com://site/ohanah.date.format', array(
   'date' => $event->start,
   'format' => 'Y-m-d H:i',
   'timezone' => 'UTC'
)));

$date_scn = new DateTime(helper('com://site/ohanah.date.format', array(
   'date' => $event->end,
   'format' => 'H:i',
   'timezone' => 'UTC'
)));

$cnt = 2; // start the termin to count at two as the first one is already defined above
$raw_ticket_type = $event->ticket_types->name;
$filter_numbers = array_filter(preg_split('/\D/', $raw_ticket_type));
$filtered_numbers = reset($filter_numbers);
$first_occurence = substr($filtered_numbers[0], 0, 1);
$final_amount = $first_occurence - 1; // subtract 1 from $first_occurence as it is always one more

for ($i = 0; $i < $final_amount; $i++)
{ // loop
    $date-- > add(new DateInterval('P1W')); //add one week
    $formatted_time = utf8_encode(strftime("%A, %d. %B %Y, %H:%M", $date->getTimestamp()));
    $formatted_time_scnpart = utf8_encode(strftime("%H:%M", $date_scn->getTimestamp()));

    // This is the modal

    echo '<div class="termin-layout"><span class="termin-number-text">' . $cnt++ . '. ' . 'Termin' . '</span>
<span class="termin-date">' . $formatted_time . ' - ' . $formatted_time_scnpart . '</span></div>';
}

echo '</div></div></div>';

您可以使用while循环而不是for循环。如果满足条件，则可以跳过增加计数器的操作。

$i = 0;
while ($i < $final_amount) {
    $date-- > add(new DateInterval('P1W'));
    if (is_holiday($date)) {
        continue;
    }
    $i++;
    $formatted_time = utf8_encode(strftime("%A, %d. %B %Y, %H:%M", $date->getTimestamp()));
    $formatted_time_scnpart = utf8_encode(strftime("%H:%M", $date_scn->getTimestamp()));

    // This is the modal

    echo '<div class="termin-layout"><span class="termin-number-text">' . $cnt++ . '. ' . 'Termin' . '</span>
<span class="termin-date">' . $formatted_time . ' - ' . $formatted_time_scnpart . '</span></div>';
}

如果日期是循环生成的，如何跳过日期？
