在PHP中減去時間（HH：MM：SS）的一串數字的方法？

Question

我想知道如果它是在PHP /笨能夠減去其在的

HH一個時間格式的值：MM：SS

例如：

$time1 = "12:45:03"; 
$time2 = "14:03:48"; 

$timelength = $time2- $time1; 

任何建議或鏈接到代碼示例？

Answer 1

這就像

//function to convert seconds into hour:minute:second 
    function sec2hms ($sec, $padHours = false) 
    { 

     // start with a blank string 
     $hms = ""; 

     // do the hours first: there are 3600 seconds in an hour, so if we divide 
     // the total number of seconds by 3600 and throw away the remainder, we're 
     // left with the number of hours in those seconds 
     $hours = intval(intval($sec)/3600); 

     // add hours to $hms (with a leading 0 if asked for) 
     $hms .= ($padHours) 
     ? str_pad($hours, 2, "0", STR_PAD_LEFT). ":" 
     : $hours. ":"; 

     // dividing the total seconds by 60 will give us the number of minutes 
     // in total, but we're interested in *minutes past the hour* and to get 
     // this, we have to divide by 60 again and then use the remainder 
     $minutes = intval(($sec/60) % 60); 

     // add minutes to $hms (with a leading 0 if needed) 
     $hms .= str_pad($minutes, 2, "0", STR_PAD_LEFT). ":"; 

     // seconds past the minute are found by dividing the total number of seconds 
     // by 60 and using the remainder 
     $seconds = intval($sec % 60); 

     // add seconds to $hms (with a leading 0 if needed) 
     $hms .= str_pad($seconds, 2, "0", STR_PAD_LEFT); 

     // done! 
     return $hms; 

    } 

    $subtracted_time = strtotime($time2) - strtotime($time1); //gives difference in seconds 
    echo(sec2hms($subtracted_time));

Answer 2

我會使用strtotime()函數將時間轉換爲UNIX時間值。然後，您可以減去這兩個值，因爲它們將是整數，然後使用date()函數以您想要的方式格式化差異。

Answer 3

作爲除了BenGC的回答

$tmp_time1 = strtotime($submit_date); 
$tmp_time2 = strtotime($submit_date); 
$timelength = $tmp_time2 - $tmp_time1; 

應該工作，我沒有測試過，但我已經使用代碼非常相似。你會得到兩次之間的秒數。

Answer 4

這是我的建議（工作PHP代碼）：

$time1 = '12:45:03'; 
$time2 = '14:03:48'; 
$timelength = strtotime($time2) - strtotime($time1); 

$hours = intval($timelength/3600); 
$minutes = intval(($timelength % 3600)/60); 
$seconds = $timelength % 60; 

echo str_pad($hours, 2, '0', STR_PAD_LEFT) . ':' . str_pad($minutes, 2, '0', STR_PAD_LEFT) . ':' . str_pad($seconds, 2, '0', STR_PAD_LEFT); 

輸出：

1時18分45秒

Answer 5

使用以下，這將有助於你

function calculate_time_past($start_time, $end_time, $format = "s") { 
     $time_span = strtotime($end_time) - strtotime($start_time); 
     if ($format == "s") 
     { // is default format so dynamically calculate date format 
      if ($time_span > 60) { $format = "i:s"; } 
      if ($time_span > 3600) { $format = "H:i:s"; } 
     } 
     return gmdate($format, $time_span); 
} 

$tdiff=calculate_time_past($time1, $time2, "H:i:s"); // will output 00:02:45 when format is overridden
