PHP加起來兩個時間變量

Question

在我的PHP應用程序中，我想計算兩個時間變量的總和。我正在尋找這樣的例子。

$time1 = 15:20:00; 
$time2 = 00:30:00; 
$time = $time1+$time2; 

Answer 1

做到這一點，最好的方法是最有可能使用的strtotime將它們轉換爲時間標記，然後進行相加在一起：

$o = strtotime($time1)+strtotime($time2);

如果我記得沒錯strtotime不支持此格式。

否則，您需要自行過濾。

Answer 2

代碼：

$time1 = '15:20:00'; 
$time2 = '00:30:00'; 
$time = strtotime($time1)+strtotime($time2); 
$sumtime = date("H:i:s",$time); 

Answer 3

你可以使用PHP 5.3 DateInterval：

$timeInterval = DateInterval::createFromDateString('15 hours + 20 minutes'); 
$timeInterval2 = DateInterval::createFromDateString('30 minutes'); 

foreach(str_split('ymdhis') as $prop) 
{ 
    $timeInterval->$prop += $timeInterval2->$prop; 
} 
var_dump($timeInterval->format('%H:%i:%s')); 

（如何添加到DateInterval對象是在這裏解釋：How we can add two date intervals in PHP）

Answer 4

至於我可以說，Sammaye的答案對我沒有幫助。

我需要開始時間，我想添加UNIX時間戳的開始。這樣，strtotime返回第一次需要添加的秒數。

$time1 = "15:20:00"; 
$time2 = "1970-01-01 00:30:00"; 
$time = strtotime($time1) + (strtotime($time2) + 3600); 
echo $time . "<br />"; 
echo date("H:i:s", $time); 

Answer 5

一定要諮詢神祕文檔http://us1.php.net/strtotime你可以輸入額外的東西進入你的功能:)

$today = time(); 
$tommorrow = strtotime("+1 days", $today); 
$day_after_tomorrow = strtotime("+1 days", $tomorrow); 

Answer 6

如果你希望答案是15:50:00，並要使用strtotime和date功能，您需要在將它們轉換爲unix時間戳時減去秒數$time1和$time2的份額：

$time1 = '15:20:00'; 
$time2 = '00:30:00'; 
$time = strtotime($time1) + strtotime($time2) - strtotime('00:00:00'); 
$time = date('H:i:s', $time); 

Answer 7

以下回答不會返回正確的值。它總結了整數，但沒有返回正確的時間。

$ o = strtotime（$ time1）+ strtotime（$ time2）;

我創建了一個函數來計算時間如下。

public function addTwoTimes($time1 = "00:00:00", $time2 = "00:00:00"){ 
     $time2_arr = []; 
     $time1 = $time1; 
     $time2_arr = explode(":", $time2); 
     //Hour 
     if(isset($time2_arr[0]) && $time2_arr[0] != ""){ 
      $time1 = $time1." +".$time2_arr[0]." hours"; 
      $time1 = date("H:i:s", strtotime($time1)); 
     } 
     //Minutes 
     if(isset($time2_arr[1]) && $time2_arr[1] != ""){ 
      $time1 = $time1." +".$time2_arr[1]." minutes"; 
      $time1 = date("H:i:s", strtotime($time1)); 
     } 
     //Seconds 
     if(isset($time2_arr[2]) && $time2_arr[2] != ""){ 
      $time1 = $time1." +".$time2_arr[2]." seconds"; 
      $time1 = date("H:i:s", strtotime($time1)); 
     } 

     return date("H:i:s", strtotime($time1)); 
    }
