PHP时间添加小时数错误

Question

I try to add hours to the server time but when I tried a tutorial I got a confusing time.

Code:

$timestamp = time();
$datum = date("d.m.Y",$timestamp);
$now = date("H:i",$timestamp);
//Actual Week Day
$dw = date( "w", $timestamp);
echo $datum," - ",$now," oclock "," Weekday ",$dw; 
//Add hours to server time
$timeadd = date("H:i", strtotime("+ 8 hours",$now));
echo " Time add = ", $timeadd;

And this is the output:

05.12.2015 - 20:55 oclock Weekday 6 Time add = 09:00

Why is the output from Time always 09:00 ?

Answer 1

This line

$timeadd = date("H:i", strtotime("+ 8 hours",$now));

needs to be:

$timeadd = date("H:i", strtotime("+ 8 hours",$timestamp));

I think you're confusing strtotime with what you're passing in, it just needs the raw timestamp that you got at the beginning with time().
