As a developer, you may encounter situations where you need to change the time zone of your PHP application. This can be necessary if your application serves users in different time zones or needs to perform time-based calculations specific to a particular time zone. In this article, we will guide you through the steps required to change the time zone of your PHP application.
In this article, you will learn how to change the time zone through PHP
Step 1: Determine the Time Zone
The first step is determining the time zone you want to use. PHP supports a list of time zones that you can use. You can find a complete list of supported time zones in the PHP documentation. Once you have determined the time zone you want to use, you must set it in your PHP code.
Step 2: Set the Time Zone
To set the time zone in your PHP code, use the date_default_timezone_set() function. This function takes a single argument, which is the name of the time zone that you want to use. Here is an example of how to set the time zone to “America/New_York”:
date_default_timezone_set('America/New_York');
You should call this function at the beginning of your PHP script before any date and time functions are called.
Step 3: Test the Time Zone
Once you have set the time zone, you should test it to ensure it works correctly. You can do this by calling the date()
You can check the timezone with PHP code using the following function:
<?phpecho date_default_timezone_get();?>
This will output the current timezone setting of your PHP server. If you want to set a different timezone, you can use the following code:
<?phpdate_default_timezone_set('America/New_York');?>
Replace ‘America/New_York’ with the timezone you want to set. You can find a list of supported time zones in the PHP documentation.
Below you can see the complete list of time zones that can be set in PHP, Please remember to substitute your desired time zone in the code below:
date_default_timezone_set('America/New_York');
