如何利用php语法做一个动态倒计时的效果，下面web建站小编给大家简单介绍一下具体实现代码！
具体代码如下：
function getSecondsLeft($targetTime)
{
$currentTime = time();
return strtotime($targetTime) - $currentTime;
}
//转换时间
function formatSeconds($num)
{
$day = floor($num / (3600 * 24));
$hours = floor(($num % (3600 * 24)) / 3600);
$minutes = floor(($num % 3600) / 60);
$seconds = $num % 60;
return array($day, $hours, $minutes, $seconds);
}
//输出倒计时
function displayCountdown($targetTime)
{
$seconds = getSecondsLeft($targetTime);
$timeArray = formatSeconds($seconds);
$countDown = "";
if ($timeArray[0] > 0) {
$countDown .= $timeArray[0] . "天";
}
$countDown .= str_pad($timeArray[1], 2, "0", STR_PAD_LEFT) . ":";
$countDown .= str_pad($timeArray[2], 2, "0", STR_PAD_LEFT) . ":";
$countDown .= str_pad($timeArray[3], 2, "0", STR_PAD_LEFT);
echo $countDown;
}
