用微秒的php增加一些时间

Question

HI I need to add 8 hours in the time which i have formatted like below

            $t = microtime(true);
            $micro = sprintf("%06d",($t - floor($t)) * 1000000);
            $d = new DateTime( date('Y-m-d H:i:s.'.$micro, $t) );
            $d->format("Y-m-d H:i:s.u")   // 2015-03-02 07:37:18.715271

i use this format because i need to show microseconds also. Now i need to add 8 hours in this .Can you please suggest me how can i do this.

thanks

Answer 1

$t = microtime(true);
$micro = sprintf("%06d",($t - floor($t)) * 1000000);
$d = new DateTime( date('Y-m-d H:i:s.'.$micro, $t) );
print $date = $d->format("Y-m-d H:i:s.u");
print $new_time = date("Y-m-d H:i:s".$micro, strtotime($date.'+8 hours'));
