PHP获取每周星期从具体的开始日期 [英] PHP Get recurring week from specific start date

问题描述

我期待到试图建立和阵列，这将是这个样子：

I'm looking into trying to set up and array that will look something like this:

$dates = array(
    [0] => "07/11/2013",
    [1] => "14/11/2013",
    [2] => "21/11/2013",
    [3] => "28/11/2013",
    [4] => "05/12/2013",
    [5] => "12/12/2013");

我愿意用这个，但我想明年再此再次发生我preFER有PHP做到这一点，它进入我的一个数组。我知道如何限制它，我希望有一个具体金额，但我不知道怎么一个星期添加到当前日期或特定的日期，如果我想启动 2013年8月11日例如

我已经快看，似乎我无法找到任何这一点。

I've had a quick look and I can't seem to find anything that does this.

我只需要一个脚本来一个星期添加到当前为止，此刻，这是逢星期四，然后添加到阵列中。

I just need a script to add a week to the current date, at the moment this is every Thursday, and then add that to the array.

我唯一的问题是我不知道如何指定一个日期，然后每次添加一个星期。我假设为循环将是最好的位置。

My only problem is I'm not sure how to specify a date, and then add a week every time. I assume a for loop would be best here.

推荐答案

使用 的DateTime 类。 DateInterval和DatePeriod类在PHP 5.3.0相继出台，所以下面的解决方案适用于仅PHP> = 5.3.0：

Use DateTime class. DateInterval and DatePeriod classes were introduced in PHP 5.3.0, so the below solution works for only PHP >= 5.3.0:

$start = new DateTime('2013-11-07');
$end = new DateTime('2013-12-31');
$interval = new DateInterval('P1W');  // one week

$p = new DatePeriod($start, $interval, $end);

foreach ($p as $w) {
    $weeks[] = $w->format('d-m-Y');
}

演示！

由于Glavic注意到，<一个href=\"http://stackoverflow.com/questions/19840912/php-get-recurring-week-from-specific-start-date/19841137#comment29529922_19841137\">comments下面，这也可以在PHP的previous版本使用完成修改（） 方式：

As Glavic notes in the comments below, this can also be done in previous versions of PHP using the modify() method:

$start = new DateTime('2013-11-07');
$end = new DateTime('2013-12-31');

$weeks = array();
while ($start < $end) {
    $weeks[] = $start->format('d-m-Y');
    $start->modify('+1 week');
}

演示。
