问题
I have following code:
$date = new DateTime(date("Y-m-d H:i:s"), new DateTimeZone('Asia/Karachi'));
echo $date->format('Y-m-d H:i:s');
Output: 2015-08-26 17:46:05
Actual Result should be: 2015-08-26 13:46:05
How to set the time zone, so that actual output comes?
回答1:
use this line in your codes
date_default_timezone_set("Asia/Karachi");
like
<?php
date_default_timezone_set("Asia/Karachi");
echo date('d-m-Y H:i:s');
?>

Method 1 (Editing Php.ini)
1) Open your php.ini file
2) Add the following line of code to top of your php.ini file
date.timezone = "Asia/Karachi"
3) Restart php.
Note: You can find a list of timezone here: http://php.net/manual/en/timezones.asia.php
Method 2 (Using date_default_timezone_set)
In case you don't have access to the php.ini file, you can use date_default_timezone_set("Asia/Karachi"). Just put it in the entry point of your application.

It is better to keep it in the config file because even if you use the same function somewhere else, you will have to re-declare this statement.
date_default_timezone_set("Asia/Karachi");
If you are using any framework like yii, CI or cake php.. keep this line in index.php file which basically later on loads rest of the framework.
