Php Set TimeZone

Question

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?

Answer 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'); 
?>

Answer 2

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.

Answer 3

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.
