Example #1 locale_get_default() example
<?php
ini_set('intl.default_locale', 'de-DE');
echo locale_get_default();
echo '; ';
locale_set_default('fr');
echo locale_get_default();
?>
Example #2 OO example
<?php
ini_set('intl.default_locale', 'de-DE');
echo Locale::getDefault();

If you don't do anything, you can still call these methods and get the server's default locale.
In the case of Linux (Ubuntu 16.04), it uses the $LANG global variable.
Using the REPL:
echo locale_get_default(); // en_US
and then resetting the $LANG:
tiikeri@ubuntu:~$ LANG="fi_FI.UTF-8"
and back to the REPL:
echo locale_get_default(); // fi_FI
