Parameters: This function accepts single parameter $timezone which is mandatory. It specify the timezone of the new DateTimeZone object to be created.
Return Value: It returns the DateTimeZone object on success or False on failure.
Exceptions: The timezone passed as a parameter must be a supported timezone in PHP else it may result in incorrect results.
Below programs illustrate the timezone_open() function in PHP:
Program 1:
<?php // Creating a new DateTimeZone object $timezone = timezone_open("America/Chicago"); echo ("The new DateTimeZone object created is " . timezone_name_get($timezone )); ?> |
The new DateTimeZone object created is America/Chicago
Program 2:
<?php // Array of timezones $timezones = array('Europe/London', 'Asia/Kolkata'); foreach ($timezones as $tz) { $name = timezone_open($tz); echo ("The new DateTimeZone object created is " . timezone_name_get($name). "<br>"); } ?> |
The new DateTimeZone object created is Europe/London
