好吧,我对此束手无策。3天来一直试图解决这个问题,但我对此一无所获。
我需要获取$offset
两个位置之间的值并将其从设定的时间(即(00:00)
.
这是我设置$offset
值的方式,它工作得很好。
<?php
if( isset($_POST['submit']))
{
//be sure to validate and clean your variables
$timezone1 = htmlentities($_POST['timezone1']);
$timezone2 = htmlentities($_POST['timezone2']);
//then you can use them in a PHP function.
function get_timezone_offset( $origin_tz, $remote_tz ) {
$timezone1 = new DateTimeZone ( $origin_tz );
$timezone2 = new DateTimeZone ( $remote_tz );
$datetime1 = new DateTime ("now", $timezone1);
$datetime2 = new DateTime ("now", $timezone2);
$offset = $timezone1->getOffset($datetime1) - $timezone2->getOffset($datetime2);
return $offset;
}
$offset = get_timezone_offset($timezone1, $timezone2);
}
?>
这就是我尝试使用 DateTime 做我想做的事情的方法,这段代码只会回显该$offset
值,而不会将其从 00:00 中删除
<?php
if (0 > $offset)
{
// set an object with the current date
$date = new DateTime();
$date->setTime(00, 00);
// the second date
$date2 = new DateTime($offset/3600 * 1);
// apply the diff() method, getting a DateInterval object ($diDiff)
$diDiff = $date->diff($date2) ;
}
echo $diDiff->format("%H:%i");
?>
我什至尝试使用strtotime
,但 strtotime 返回错误的值,stackoverflow 上的一些人建议我使用 DateTime。
<?php
$time1 = strtotime('00:00');
if (0 > $offset)
{
// For negative offset (hours behind)
$hour_dif = date('H:i', strtotime($time1 -$offset/3600));
$time1 = "{$hour_dif}";
}
elseif (0 < $offset)
{
// For positive offset (hours ahead)
$hour_dif = date('H:i', strtotime($time1 +$offset/3600));
$time1 = "{$hour_dif}";
}
else
{
// For offsets in the same timezone.
$time1 = "in the same timezone";
}
echo "{$time1}";
?>
请有人帮助我,因为这绝对是在浪费我的时间。
