如何打印剩余时间

Question

这是我的表格。 dateline列以小时为单位。

如何根据dateline，created_at和当前时间打印剩余小时数？

Answer 1

您可以使用strtotime()：

<?php 

$created = 1323504315; 
$timeleft = 144; 
$expires = strtotime("+$timeleft hours", $created); 

$compare_text = "created: " . date('m/d/Y H:i A',$created) . ", now: " . date('m/d/Y H:i A') . " > expires:" . date('m/d/Y H:i A',$expires); 

if (mktime() > $expires) { 
    echo "The time has expired. ($timeleft, $compare_text)"; 
} else { 
    echo "The time has not expired. ($timeleft, $compare_text)"; 
} 

?>

Answer 2

 
$hours = "144"; //from dataline 
$totalHours = date("H") - $hours; 

$totalMinutes = date("i"); 

$totalSeconds = date("s"); 

$totalMonths = date("m"); 

$totalDays = date("d"); 

$totalYears = date("Y"); 

$timeStamp = mktime($totalHours, $totalMinutes, $totalSeconds, $totalMonths, $totalDays, $totalYears); 

$myTime = date("H:i A", $timeStamp);
