如何使用PHP确定周范围？

我试图用PHP确定星期一到星期天的范围。我能够计算周数，但我无法为每个星期获得正确的结束周范围

以下是我到目前为止的情况：

$start_date = 1337621424;
$end_date = 1349964545;

$start_week = (int)date('W', $start_date); 
$end_week = (int)date('W', $end_date); 

echo "START WEEK: " . $start_week . "<BR>";
echo "END WEEK: " . $end_week . "<BR>";

$dates = array();

if ($start_week && $end_week) {

    for ($week=$start_week; $week<=$end_week; $week++) {
        echo "WEEK: " . $week . "<BR>";

        $startdate = strtotime ( '- ' . $week. ' week', strtotime ( date('Y-m-d') ) ) ;
        $startdate = date ( 'Y-m-d' , $startdate );

        //$end = date('Y-m-d');
        $end = strtotime ( '- ' . ($week + 1) . ' week', strtotime ( $startdate ) ) ;
        $end = date ( 'Y-m-d' , $end );

        $dates[$week]['start'] = $startdate;
        $dates[$week]['end'] = $end;
    }

    print_r($dates);
}   

$start\u date=1337621424；
$end_date=1349964545；
$start_week=（int）日期（'W'，$start_date）；
$end_week=（int）日期（'W'，$end_date）；
回声“开始周：”$开始一周。“
”；
回声“周末：”$周末。“
”；
$dates=array（）；
如果（$start_week&$end_week）{
对于（$week=$start\u week；$week您可以尝试

$startDate = new DateTime();
$startDate->setTimestamp(1337621424);

$endDate = new DateTime();
$endDate->setTimestamp(1349964545);

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

    $dates[$startDate->format("W")] = $week ;
}
var_dump($dates);

$startDate=new DateTime（）；
$startDate->setTimestamp（1337621424）；
$endDate=新的日期时间（）；
$endDate->setTimestamp（1349964545）；
$dates=array（）；
而（$startDate格式（“Y-m-d”）；
$startDate->modify（“+1周”）；
$week['end']=$startDate->格式（“Y-m-d”）；
$dates[$startDate->format（“W”）]=$week；
}
var_dump（日期）；
您正在从开始日期开始操作
（$week+1）周。
