PHP中的时区转换不会改变日期值

Question

我有以下代码…

    $stored_date = date_format(date_create('now'), 'Y-m-d H:i:s');
    echo 'Stored date: ' . $stored_date . "<br/>";
    $user_timezone = 'Australia/Brisbane';

我想转换$stored_date(它是基于服务器的时区创建的)为基于$user_timezone的日期或日期的字符串表示形式。

我想使用过程PHP代码而不是OO代码。

I have try .

   date_create($stored_date, timezone_open($user_timezone));

但这似乎没有给出一个正确的答案。

如果$stored_date is '2011-11-15 23:45:35'与服务器的时区是'America/Toronto'，我得到的结果是相同的'2011-11-15 23:45:35'。

然而，date_create('now', timezone_open($user_timezone));似乎可以工作并根据$user_timezone给出正确的日期。

你知道我做错了什么吗?

谢谢

你应该试试这个。

$time = date_format(date_create('now'), 'Y-m-d H:i:s');
$tz = "Australia/Brisbane";
// create the DateTimeZone object for later
$dtzone = new DateTimeZone($tz);
// now create the DateTime object for this time and user time zone
$dtime = new DateTime($time,$dtzone);
// print the timestamp
$timestamp = $dtime->format('U');
//ultimate time according to timezone you have specified              
$time_final = gmdate("Y-m-d H:i:s",$timestamp); 

希望这对你有帮助。
