PHP+JS implementation of product seconds Kill Countdown Usage Example _php tips

The example of this article tells the PHP+JS implementation of the product seconds to kill countdown usage. Share to everyone for your reference, specific as follows:

the time of <?php//php is in seconds. JS time in milliseconds
date_default_timezone_set (' PRC ');
Date_default_timezone_set ("Asia/hong_kong");/
/region//Configure daily activity time period
$starttimestr = "2016-3-29 8:10:00";
$endtimestr = "2016-3-29 9:43:00";
$starttime = Strtotime ($STARTTIMESTR);
$endtime = Strtotime ($ENDTIMESTR);
$nowtime = time ();
if ($nowtime < $starttime) {
die ("activity has not yet started, activity time is: {$starttimestr} to {$endtimestr}");
}
if ($endtime >= $nowtime) {
$lefttime = $endtime-$nowtime;//The actual remaining time (seconds)
 }else{
 $lefttime =0;
 Die ("Activity is over!") ");
}
? >

<script language= "JavaScript" > var runtimes = 0; function Getrtime () {var NMS = <?php echo $lefttime;?>*1000-runtimes*1000; if (nms>=0) {var nd=math.floor (1
000*60*60*24))%24;
var Nh=math.floor (nms/(1000*60*60))%24;
var Nm=math.floor (nms/(1000*60))% 60;
var ns=math.floor (nms/1000)% 60;
document.getElementById ("Remaind"). Innerhtml=nd;
document.getElementById ("Remainh"). Innerhtml=nh;
document.getElementById ("REMAINM"). innerhtml=nm;
document.getElementById ("remains"). Innerhtml=ns; if (nms==5*60*1000) {alert ("Last five minutes!")
");
}
runtimes++;
SetTimeout ("Getrtime ()", 1000);
} var Num = 0;
 onload = function () {Refresh ();
 SetInterval ("Refresh ();", 100);
Getrtime ();
 function Refresh () {if (num<10) {document.getElementById ("Remainl"). InnerHTML = Num;
 num = num + 1;
 }else{num=0; } </script>
