Проблема с функцией даты в PHP

Question

Я работаю над еженедельным расписанием.

Я генерирую неделю на основе текущей даты. См. Следующий код.

<?php 
    $date = mktime(0, 0, 0, date('m'), date('d'), date('Y')); 
    $week = (int)date('W', $date); 
    $year = date('Y');

    for($day=1; $day<=7; $day++)
    {
        echo date('M dS, Y', strtotime($year."W".$week.$day));
    }
?>

Это работает нормально, но когда я пытаюсь перемещаться между неделями, я сталкиваюсь с проблемами. На 9 неделе у меня дата 01-03-1970. Это не генерирует даты недели для февраля.

Также пробовал со статической датой 03-02-2012, но получал такую ​​же случайную дату.

$week =9; //(int)date('W', $date);

В другом выпуске

echo date('N', strtotime('03-09-2012'));

над возвращением satement 1. Я не убежден в результате здесь.

Пожалуйста, дайте мне знать, что я должен сделать, чтобы прийти с этим или помочь мне найти способ не знать дня недели для данной даты.

Answer 1

Я не знаю, какую версию PHP вы используете, но вам следует использовать объект DateTime с DateInterval

Это намного лучше и прощеиспользовать.

Answer 2

Попробуй это.У меня отлично работает:

<?php 
if(isset($_GET['diffweek'])){
  $diffweek=$_GET['diffweek'];
}else{
  $diffweek=0;}

$date = mktime(0, 0, 0, date('m'), date('d'), date('Y')); 
$week = date('W', $date+$diffweek*604800); 
$year = date('Y');

for($day=1; $day<=7; $day++)
  {
  echo date('M dS, Y', strtotime($year."W".$week.$day));
  echo '<hr>';
  }

echo '<a href="?diffweek='.($diffweek-4).'">4 weeks back</a><br>';
echo '<a href="?diffweek='.($diffweek-1).'">prew. week</a><br>';
echo '<a href="?diffweek=0">this week</a><br>';
echo '<a href="?diffweek='.($diffweek+1).'">next week</a><br>';
echo '<a href="?diffweek='.($diffweek+4).'">4 week later</a><br>';
?>

Answer 3

с использованием класса DateTime (PHP 5> = 5.2.0):

    $date = date_create();

    for($d=1; $d<=7; $d++){

        echo $date->format('M dS, Y')."<br />";         
        $date->modify('+1 day');

    }

Answer 4

Попытка сохранить решение как можно ближе к вашему текущему коду.

Для вашей проблемы 1970 года:

Похоже, что strtotime требует, чтобы номера недель, начинающиеся с нуля, работали правильно для тех недель до 10, в противном случае он выводится в 1970, игнорируягод (мне это кажется ошибкой?).Тем не менее, поддержка недель и дней недели отсутствует в официальной документации для strtotime.

Поэтому я бы заменил

    $week = (int)date('W', $date); 

на:

    $week = str_pad(date('W', $date),2,'0',STR_PAD_LEFT);

Относительно следующего кода:

    echo date('N', strtotime('03-09-2012'));

Возвращает 1 (понедельник), поскольку strtotime интерпретирует 03-09-2012 в британском формате дм. в отличие от американского формата mdY.Чтобы избежать путаницы, вы должны использовать формат даты ISO Ymd .См. Руководство PHP по форматам даты для получения дополнительной информации.

Так что если вы хотите 9 марта 2012 года, вы бы написали:

    echo date('N', strtotime('2012-03-09'));

Надеюсь, это поможет!

Answer 5

Следующий код

$ts = mktime(0, 0, 0, 4, 5, 2012);

$offset = date('N', $ts);

for ($i = 1 - $offset, $j = 0; $j++ < 7; $i++) {
    echo date('r', $ts + $i * 3600 * 24) . "\n";
}

выводит дни недели, к которым относится указанный день:

Apr 02nd, 2012
Apr 03rd, 2012
Apr 04th, 2012
Apr 05th, 2012
Apr 06th, 2012
Apr 07th, 2012
Apr 08th, 2012

Надеюсь, это то, что вы искали.

Какдля проблемы с strtotime проверьте, является ли возвращаемая дата действительно датой, после которой вы выполнили

echo date('r', strtotime('03-09-2012'));

Безопаснее передавать дату в strtotime как YYYY-MM-DD.

Answer 6

Это может помочь вам.Это функция для возврата календарных дат данного года:

<code><?php

  /**
   * Get all the dates in the given year's calendar
   *
   * @param NULL|integer $year
   * @param string $format
   * @return array
   */
  function getCalendar($year = NULL, $format = 'Y-m-d')
  {

    // If the year is not set then use the current
    if (!isset($year))
    {
      $year = date('Y');
    }

    // Get the first day of the year
    $start = $year . '-01-01';

    // Iterate over an incremental day increase
    for ($d = 0; ; ++$d)
    {

      // Get the date
      $date = strtotime($start . " + $d day");

      // Return the current list of dates if the current date is for next year
      if ($date >= strtotime($year + 1 . '-01-01'))
      {
        return $dates;
      }

      // Get the week number
      $w = ceil(($d + 1) / 7);

      // Add the date to the array
      $dates[isset($dates[$w][7]) ? ++$w : $w][date('N', $date)] = date($format, $date);

    }

    // Return the dates array
    return $dates;

  }

  // Get the calendar for 2012
  echo '<pre>' . print_r(getCalendar(2012, 'M dS, Y'), true) . '

';

Будет выведено:

Как вы можете видеть, оно имеет вид $array[$week_number][$day_number] (где $day_number из 1 - понедельник, а 7 - воскресенье) и$week_number будет составлять до 53 или 54 (в зависимости от года).

Затем вы можете получить даты конкретной недели, используя:

$calendar = getCalendar();

$calendar[9];

// Or if you have PHP 5.4.0

getCalendar()[9];

Я намеренно не включил днис предыдущего или следующего года в начале и конце.

Answer 7

Это должно работать для вас. «Сегодня» в первой строке можно изменить на любую дату, на которую вы хотите его проверить.

<?php 
$today = strtotime('today');
$startWeek = strtotime(date('o-\\WW', $today));
$date = mktime(0, 0, 0, date('m', $startWeek), date('d', $startWeek), date('Y', $startWeek)); 
$week = (int)date('W', $date); 
$year = date('Y', $date);

for($day=0; $day < 7; $day++)
{
    echo date('M dS, Y', $today + ($day * 24 * 60 * 60)), "\n";
}
?>

Надеюсь, это поможет.

Answer 8

Я думаю, что недели в strtotime должны быть отформатированы как год недели недели, то есть 2012-W14-3.

for ($day=1; $day<=7; $day++) {
    echo date('M dS, Y', strtotime(date('Y') ."-W". date('W') .'-'. $day));
}
