timezone_identifier_list() - PHP

timezone_identifier_list()

To know all the time zones we can set by using date_default_timezone_set()function can be listed by using timezone_identifiers_list() . This function will return an array with list of time zones available. Here is the code to list all time zones.

<?Php
$a = timezone_identifiers_list();
while (list ($key, $val) = each ($a)) {
echo "$key -> $val <br>";
} 
?>

Note that this way we can give an option to the users to select a time zone. Try to display a drop down list by taking data from the above array.
