microtime到秒或小時或分鐘轉換

Question

我有商店開始時間microtime（）和結束時間microtime（）到數據庫。

現在我想計算腳本花費多少時間來執行秒/分鐘/小時。

我該怎麼做PHP？

Answer 1

基本上，這樣的：

echo date("H:i:s",$endtime-$starttime); 

$endtime-$starttime給出秒的持續時間，date用於格式化的輸出。聽起來像保存和讀取數據庫不是你的問題，所以我把它留在我的例子中。請注意，您必須使用microtime(true)才能正常工作，使用空間分離的輸出microtime()您無法輕鬆進行計算。

編輯：你可能也做你自己的所有計算。這只是基本的數學是這樣的：

$duration = $endtime-$starttime; 
$hours = (int)($duration/60/60); 
$minutes = (int)($duration/60)-$hours*60; 
$seconds = (int)$duration-$hours*60*60-$minutes*60; 

Answer 2

如果你有時間A和時間B，以秒計，那麼這兩項絕對時間之間的秒數爲：

B - A 

如果你想要格式化此秒數，您可以使用date來對其進行美化。

Answer 3

microtime to seconds or hours or min conversion？

microtime中是PHP功能，在微秒返回時間的措施，基本上微秒可以轉換爲名稱：

 

    1 milliseconds = 1,000 microseconds 
    1 second  = 1,000,000 microseconds 
    1 minute  = 60,000,000 microseconds 
    1 hour   = 3,600,000,000 microseconds 


    or 


    1 microsecond = 0.001 milliseconds 
    1 microsecond = 0.000001 seconds 
    1 microsecond = 0.0000000166666667 minutes 
    1 microsecond = 0.000000000277777778 hours 

Answer 4

function formatPeriod($endtime, $starttime) 
    { 

    $duration = $endtime - $starttime; 

    $hours = (int) ($duration/60/60); 

    $minutes = (int) ($duration/60) - $hours * 60; 

    $seconds = (int) $duration - $hours * 60 * 60 - $minutes * 60; 

    return ($hours == 0 ? "00":$hours) . ":" . ($minutes == 0 ? "00":($minutes < 10? "0".$minutes:$minutes)) . ":" . ($seconds == 0 ? "00":($seconds < 10? "0".$seconds:$seconds)); 
} 

Answer 5

.heading { 
    color: #666; 
    border-bottom: 1px dotted #ddd; 
    font-weight: normal; 
} 
.intro { 
    color: #666; 
    background: #f5f5f5; 
    border: 1px solid #ccc; 
    border-radius: 2px; 
    padding: 10px; 
} 

<h1 class="heading">Someo Coole!</h1> 
<p class="intro">I am a very little boy! Thanks for letting me do some stuff here and around here!</p> 
<p>Sorry for taking place for none!</p> 

function formatPeriod($endtime, $starttime) 
{ 
$duration = $endtime - $starttime; 

$hours = (int) ($duration/60/60); 

$minutes = (int) ($duration/60) - $hours * 60; 

$seconds = (int) $duration - $hours * 60 * 60 - $minutes * 60; 

return ($hours == 0 ? "00":$hours) . ":" . ($minutes == 0 ? "00":($minutes < 10? "0".$minutes:$minutes)) . ":" . ($seconds == 0 ? "00":($seconds < 10? "0".$seconds:$seconds)); 
}
