Php 查找两周数字之间所有周的开始和结束日期

我正在尝试获取两周数字之间的所有周的开始日期和结束日期

这是我的一个日期是2014-05-17，周数是20，另一个日期是2014-08-13，周数是33。 我的任务是获得20到33之间所有周的开始和结束日期。这里星期天是一周的开始，星期六是一周的结束

$signupweek='2014-05-17';
$signupweek=date("W",strtotime($signupdate));

//week number of current date.
$weekNumber = date("W");

---

任何人都可以帮助查找日期。

下面是一个从以下位置实现该函数的示例：

$signupweek='2014-05-17'；
$signupweek=日期（“W”，标准时间（$signupweek））；
$current_week=日期（'W'）；
$output=array（）；
//在给定的两周之间循环一周
//若要包括开始和结束周，请删除下面的+1，并使
//它是$i time（）或strottime（$dates['end']）>time（）
继续；
//添加到输出数组
$output[]=$dates；
}
函数getStartAndEndDate（$week，$year）
{
$time=strottime（“1月1日$year”，time（））；
$day=日期（'w'，$time）；
$time+=（（7*周）+1-$day）*24*3600；
$return['start']=日期（'Y-n-j'，$time）；
$time+=6*24*3600；
$return['end']=日期（'Y-n-j'，$time）；
return$return；
}

试试这个：

$startTime = "2014-05-17";
$startWeek = 20;
$endWeek = 33;

for ($i = 0; $i <= ($endWeek - $startWeek); $i++) {
    $days = $i * 7;
    echo date("Y-m-d", strtotime($startTime . "+$days day")).'<br />';
}

$startTime=“2014-05-17”；
$startWeek=20；
$endWeek=33；
对于（$i=0；$i另一种方法

如果您有一个
日期
，从该日期开始，您可以找到该
周的
开始日期
和
结束日期
。但此处不使用
周数

例如：

您有一个
日期
2014-08-13，然后所需的
开始日期
为2014-08-10，
结束日期
为2014-08-16

PHP代码是

   $signupweek='2014-8-13';
/*start day*/
    for($i = 0; $i <7 ; $i++)
    {
     $date = date('Y-m-d', strtotime("-".$i."days", strtotime($signupweek)));
     $dayName = date('D', strtotime($date));
     if($dayName == "Sun")
     {
       echo "start day is ". $date."<br>";
     }
    }
/*end day*/
 for($i = 0; $i <7 ; $i++)
    {
     $date = date('Y-m-d', strtotime("+".$i."days", strtotime($signupweek)));
     $dayName = date('D', strtotime($date));
     if($dayName == "Sat")
     {
       echo "end day is ". $date."<br>";
     }
    }

希望这有用。
试试这个

$signupdate='2014-05-17';
$signupweek=date("W",strtotime($signupdate));
$year=date("Y",strtotime($signupdate));
$currentweek = date("W");

for($i=$signupweek;$i<=$currentweek;$i++) {
    $result=getWeek($i,$year);
    echo "Week:".$i." Start date:".$result['start']." End date:".$result['end']."<br>";
}

function getWeek($week, $year) {
  $dto = new DateTime();
  $result['start'] = $dto->setISODate($year, $week, 0)->format('Y-m-d');
  $result['end'] = $dto->setISODate($year, $week, 6)->format('Y-m-d');
  return $result;
}

现在可以使用DateTime获取一周的开始/结束日期

对于优秀的程序员来说，这似乎是一个挑战
start day is 2014-08-10
end day is 2014-08-16

$signupdate='2014-05-17';
$signupweek=date("W",strtotime($signupdate));
$year=date("Y",strtotime($signupdate));
$currentweek = date("W");

for($i=$signupweek;$i<=$currentweek;$i++) {
    $result=getWeek($i,$year);
    echo "Week:".$i." Start date:".$result['start']." End date:".$result['end']."<br>";
}

function getWeek($week, $year) {
  $dto = new DateTime();
  $result['start'] = $dto->setISODate($year, $week, 0)->format('Y-m-d');
  $result['end'] = $dto->setISODate($year, $week, 6)->format('Y-m-d');
  return $result;
}
