Here is an update to the above which has Antarctica spelled correctly and also deals with multiple
cities such as argentina etc:
<?php
$timezone_identifiers = DateTimeZone::listIdentifiers();
foreach( $timezone_identifiers as $value ){
if ( preg_match(
'/^(America|Antarctica|Arctic|Asia|Atlantic|Europe|Indian|Pacific)\//', $value ) ){
$ex=explode("/",$value);//obtain continent,city
if ($continent!=$ex[0]){
if ($continent!="") echo '</optgroup>';
echo '<optgroup label="'.$ex[0].'">';
}
if(isset($ex[2])) $city=$ex[1]."/".$ex[2];
else $city=$ex[1];
$continent=$ex[0];
echo '<option
value="'.$value.'">'.$city.'</option>';
}
}
?>
</optgroup>
</select>
