检查日期范围内有多少个周末

Question

如何检查Laravel在$from和$to之间的给定日期范围内有多少个周六或周日？

Answer 1

你可以用普通的PHP这样做：

$start = new DateTime('2016-07-07'); 
$end = new DateTime('2016-07-27'); 

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

$saturdays = 0; 
foreach($daterange as $date){ 
    $days = $date->format('D'); 
    if ($days == 'Sat') { 
     $saturdays++; 
    } 
} 

echo $saturdays;
