因此，我想做的是基于mysql的日期进行倒计时，并使其在实时模式下下降而无需刷新。
代码：
<?php
$date = strtotime($row_tournaments['date']);
$remaining = $date - time();
$days_remaining = floor($remaining / 86400);
$hours_remaining = floor(($remaining % 86400) / 3600);
$minutes_remaining = floor(($remaining % 3600) / 60);
$seconds_remaining = ($remaining % 60);
echo "<p>$days_remaining <span style='font-size:.3em;'>dias</span> $hours_remaining <span style='font-size:.3em;'>horas</span> $minutes_remaining <span style='font-size:.3em;'>minutos</span> $seconds_remaining <span style='font-size:.3em;'>segundos</span></p>";
?>
这个工作正常，但我需要刷新，这样我才能看到时间减少了。
$date = strtotime($row_tournaments['date']);
这是从数据库中获取日期，其格式为：
2015-10-11 08:15:31
var initialTime = 194801;//Place here the total of seconds you receive on your PHP code. ie: var initialTime = <? echo $remaining; ?>;
var seconds = initialTime;
function timer() {
var days = Math.floor(seconds/24/60/60);
var hoursLeft = Math.floor((seconds) - (days*86400));
var hours = Math.floor(hoursLeft/3600);
var minutesLeft = Math.floor((hoursLeft) - (hours*3600));
var minutes = Math.floor(minutesLeft/60);
var remainingSeconds = seconds % 60;
if (remainingSeconds < 10) {
remainingSeconds = "0" + remainingSeconds;
}
document.getElementById('countdown').innerHTML = days + "dias " + hours + "horas " + minutes + "minutos " + remainingSeconds+ "segundos";
if (seconds == 0) {
clearInterval(countdownTimer);
document.getElementById('countdown').innerHTML = "Completed";
} else {
seconds--;
}
}
var countdownTimer = setInterval('timer()', 1000);<span id="countdown" class="timer"></span>本文收集自互联网，转载请注明来源。
