这是代码的工作方式使用下拉菜单/选择国家/地区 - 城市 - （时区）我的问题是如何将城市和时区与国家分开。
请帮助我。
html code
<label for="timeZone"><br>City<br />
<select id="timeZone" name="timeZone">
<?php echo displayTimeZoneSelect("Europe/Amsterdam");
?>
</select>
</label>
PHP CODE
/**
* returns a HTML formated TimeZone select
*
* @param $selectedTimeZone string The timezone marked as "selected"
* @return string
*/
function displayTimeZoneSelect($selectedTimeZone = 'America/New_York'){
$countryCodes = getCountryCodes();
$return = null;
foreach ($countryCodes as $country => $countryCode) {
$timezone_identifiers = DateTimeZone::listIdentifiers(DateTimeZone::PER_COUNTRY,$countryCode);
foreach( $timezone_identifiers as $value ){
/* getTimeZoneOffset returns minutes and we need to display hours */
$offset = getTimeZoneOffset($value)/60;
/* for the GMT+1 GMT-1 display */
$offset = ( substr($offset,0,1) == "-" ? " (GMT" : " (GMT+" ) . $offset . ")";
/* America/New_York -> America/New York */
$displayValue = (str_replace('_',' ',$value));

我误解了你的问题。
您需要使用javascript来实现目标。将时区发送到服务器后，您需要以JSON格式编码城市数组并将其回送给客户端。然后，客户端将捕获该响应并填充另一个选择字段。
我建议使用jQuery AJAX。
