chema's version below has missing and mistyped continents. The following code will work well
with both PHP 5.2 and PHP 5.3:
<?php
function getTimeZoneOptions() {
$tzids = defined('DateTimeZone::ALL') ? DateTimeZone::listIdentifiers(DateTimeZone::ALL)
: DateTimeZone::listIdentifiers();
ksort($tzids);
$continent = '';
$rv = '';
foreach ($tzids as $tzid) {
if (preg_match( '/^(Africa|America|Antarctica|Arctic|Asia|Atlantic|'
. 'Australia|Europe|Indian|Pacific)\/(.*)$/', $tzid, $m)) {
if ($m[1] != $continent) {
if ($rv) {
$rv .= "</optgroup>\n";
}
$rv .= sprintf("<optgroup label=\"%s\">\n", htmlspecialchars($m[1]));
}
$continent = $m[1];
$city = str_replace('_', ' ', $m[2]);
$rv .= sprintf("\t<option value=\"%s\">%s</option>\n",
htmlspecialchars($tzid), htmlspecialchars($city));
} else {
if (defined('DateTimeZone::ALL')) {
$tz = str_replace('_', ' ', $tzid);
$rv .= sprintf("<optgroup label=\"%s\">\n\t<option
value=\"%s\">%s</option>\n</optgroup>\n",
htmlspecialchars($tz), htmlspecialchars($tzid), htmlspecialchars($tz));
}
}
}
$rv .= "</optgroup>\n";
return $rv;
}
?>
<html><body><form><select id="timezone" name="timezone">
<?php echo getTimeZoneOptions(); ?>
</select><input type='submit'/></form></body></html>
