Even though the manual currently says that the first parameter has to be "One of DateTimeZone class constants", you may actually combine these constants:

<?php
  $a
= DateTimeZone::listIdentifiers(DateTimeZone::AFRICA); //gives africa time zones
 
$b = DateTimeZone::listIdentifiers(DateTimeZone::AMERICA); //gives american time zones
 
$c = DateTimeZone::listIdentifiers(DateTimeZone::AFRICA | DateTimeZone::AMERICA); //gives both african and american time zones
?>

Be sure to use |, not ||.

Beware that the ISO 3166-1 country code passed to second parameter $country has to be in capital letters (eg. 'US', 'DE', ...).
Passing the country code in lower case like 'us' or 'de' will not return the failure-value false but just an empty array.
