How to convert datetime to another datetimezone in php???

[hmdnawaz]

I have a varaiable which gets the server time;

$date =date("Y-m-d H:i:s");

suppose the server is in the USA then it the timezone of this date will be the timezone of USA.

 

And i want to convert this timezone to Asia/Karachi timezone.

 

Any Idea about this???

putenv adds setting to the server environment. The environment variable will only exist for the duration of the current request. At the end of the request the environment is restored to its original state.

 

so the code would be

-set timezone first to Asia/Karachi

-set $date as the current time in Asia/Karachi (this happens because the server environment is now set to that timezone)

-print out the date and time

 

putenv("TZ=Asia/Karachi");
$date=date("Y-m-d H:i:s");
echo $date;

 

thats all you need to do
