从PHP中的特定日期开始上一天和后7天？

Question

获取特定日期之前和之后的7天

$date = new DateTime();
$today = $date->format('m d, Y');

如何从今天的$ $获得之前的7天和接下来的7天？并将它们循环到一个数组中.

Answer 1

与其他答案有所不同但是怎么样

$start   = new DateTime();
$end     = new DateTime();

$start   = $start->modify( '-7 days' ); 
$end     = $end->modify( '+8 days' ); // Date Period doesn't include the end date

$interval = new DateInterval('P1D');
$daterange = new DatePeriod($start, $interval ,$end);

foreach($daterange as $date){
    echo $date->format("'m d, Y'") . "<br>";
}
