Beispiel #1 A timezone_identifiers_list() example
<?php
$timezone_identifiers = DateTimeZone::listIdentifiers();
for ($i=0; $i < 5; $i++) {
echo "$timezone_identifiers[$i]\n";
}
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
Africa/Abidjan Africa/Accra Africa/Addis_Ababa Africa/Algiers Africa/Asmara
I use this time zone select:
<select id="TIMEZONE" name="TIMEZONE">
<?php
$timezone_identifiers = DateTimeZone::listIdentifiers();
foreach( $timezone_identifiers as $value ){
if ( preg_match( '/^(America|Antartica|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].'">';
}
$city=$ex[1];
$continent=$ex[0];
echo '<option value="'.$value.'">'.$city.'</option>';
}
}
?>
</optgroup>
</select>
