我想计算expiry date percentage.But我starting date和expirydate是m/d/Y format.How我会找到starting date和ending date之间的天数存储在M/d/Y格式的两个日期之间的天数???这是我的代码...

foreach ($result['query'] as $row) { 
      $validitystart = $row->validitystart; 
      $expirydate = $row->expirydate; 
      $today = date('m/d/Y'); 
      $maxdiff = date_diff($expirydate, $validitystart); 
      $diff = date_diff($expirydate, $today); 
      $percentage = ($diff * 100)/$maxdiff; 
     }

其中数百个重复的这里在计算器上，你可能会发现像这样带着几分搜索

$date1 = DateTime::createFromFormat('m/d/Y', $date1); 
$date2 = DateTime::createFromFormat('m/d/Y', $date2); 

$diffDays = $date2->diff($date1)->format("%a");
