PHP加起来两个时间变量

Question

在我的PHP应用程序中，我想计算两个时间变量的总和。我正在寻找这样的例子。

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

Answer 1

做到这一点，最好的方法是最有可能使用的strtotime将它们转换为时间标记，然后进行相加在一起：

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

如果我记得没错strtotime不支持此格式。

否则，您需要自行过滤。

Answer 2

代码：

$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对象是在这里解释：How we can add two date intervals in PHP）

Answer 4

至于我可以说，Sammaye的答案对我没有帮助。

我需要开始时间，我想添加UNIX时间戳的开始。这样，strtotime返回第一次需要添加的秒数。

$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

一定要咨询神秘文档http://us1.php.net/strtotime你可以输入额外的东西进入你的功能:)

$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，并要使用strtotime和date功能，您需要在将它们转换为unix时间戳时减去秒数$time1和$time2的份额：

$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

以下回答不会返回正确的值。它总结了整数，但没有返回正确的时间。

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

我创建了一个函数来计算时间如下。

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)); 
    }
