php中倒计时的问题
清风a50 2014-07-13 02:03:28 源代码是这样的
$time1=strtotime(date("Y-m-d H:i:s"));
$time2=strtotime("2014-11-11 00:00:00");
$time3=strtotime("2013-01-01");
$sub1=ceil(($time2-$time1)/3600);
$sub2=ceil(($time3-$time1)/86400);
echo $time2."<br>";
echo $time1."<br>";
echo "距离时间<font color=red>$sub1</font>";
?>
最后输出的结果是
Strict Standards: strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'UTC' for '8.0/no DST' instead in D:\AppServ\www\base1\strcmp.php on line 18
