php - 以最早到最新的顺序列出随机日期

Question

您如何列出随机日期（从最早到最新）？

我一直在尝试使用 PHP 来实现这一点，但没有成功。我可以得到一个随机的日期来显示，但会一遍又一遍地循环相同的日期，而不是创建新的日期并按指定的顺序列出它们。

到目前为止，这是我的代码：

// Create a random date between 2 months
$datestart = strtotime('01-11-2012');
$dateend = strtotime('01-12-2012');
$daystep = 86400;
$datebetween = abs(($dateend - $datestart) / $daystep);
$randomday = rand(0, $datebetween);

for($i=0; $i< rand(10, 30) ;++$i)
{
echo "<div>" . date("d/m/Y", $datestart + ($randomday * $daystep)) ."</div>";
}

更新：感谢Mihai Iorga，我现在已经设法让代码正常工作，但仍然存在将日期从最旧到最新排序的问题。我如何做到这一点：

// Create a random date between 2 months
$datestart = strtotime('01-11-2012');
$dateend = strtotime('01-12-2012');
$daystep = 86400;
$datebetween = abs(($dateend - $datestart) / $daystep);
$randomday = rand(0, $datebetween);

for($i=0; $i< rand(10, 30) ;++$i)
{
$randomday = rand(0, $datebetween);
echo "<div>" . date("d/m/Y", $datestart + ($randomday * $daystep)) ."</div>";
}

Answer 1

$datestart = strtotime('01-11-2012');
$dateend = strtotime('01-12-2012');
$daystep = 86400;
$datebetween = abs(($dateend - $datestart) / $daystep);
$dateArray[] = date("d/m/Y");
$randomday = rand(0, $datebetween);

for($i=0; $i< rand(10, 30) ;++$i)
{
     $randomday = rand(0, $datebetween);
     $randomdate = date("d/m/Y", $datestart + ($randomday * $daystep));
     $dateArray[] = $randomdate;
}

sort($dateArray);

foreach ($dateArray as $d) 
{ 
   echo "<div>" . $d ."</div>";
} 

在http://writecodeonline.com/php/上测试代码并运行此输出：

05/11/2012
06/11/2012
07/11/2012
08/11/2012
08/11/2012
12/11/2012
12/11/2012
12/11/2012
19/11/2012
20/11/2012
24/11/2012
27/11/2012
28/11/2012
30/11/2012

Answer 2

你可以试试

$dateStart = new DateTime();
$dateStart->setDate(2012, 11, 01);

$dateEnd = new DateTime();
$dateEnd->setDate(2012, 12, 01);

$dates = array();
while ( $dateStart < $dateEnd ) {
    $dates[] = $dateStart->format("d/m/Y");
    $dateStart->modify(sprintf("+%d day",mt_rand(1, 10)));
}

var_dump($dates);

输出

array
  0 => string '01/11/2012' (length=10)
  1 => string '07/11/2012' (length=10)
  2 => string '14/11/2012' (length=10)
  3 => string '20/11/2012' (length=10)
  4 => string '27/11/2012' (length=10)
  5 => string '28/11/2012' (length=10)
