用于时区的PHP变量

Question

I'm asking about PHP contants for timezones name

For Example :

$rc = date_default_timezone_set("US/Mountain");

"US/Mountain" to be constants not write it as text

is it exist from PHP classes or I need to do it myself

Thanks in advance

Answer 1

There's no such a thing as a predefined constant for this because simply it's not needed. date_default_timezone_set works with a string. If you want a constant then you can define one yourself:

define('MY_CONSTANT', "US/Mountain");

and obviously use it as:

date_default_timezone_set(MY_CONSTANT);
