PHP Timezone List
I am looking for a way to generate a list of timezones for display in a <select> Generating a drop down list of timezones with PHP
$list = DateTimeZone::listAbbreviations();
$idents = DateTimeZone::listIdentifiers();
$data = $offset = $added = array();
foreach ($list as $abbr => $info) {
foreach ($info as $zone) {
if ( ! empty($zone['timezone_id'])
AND
! in_array($zone['timezone_id'], $added)
AND
in_array($zone['timezone_id'], $idents)) {
$z = new DateTimeZone($zone['timezone_id']);
$c = new DateTime(null, $z);
$zone['time'] = $c->format('H:i a');
$data[] = $zone;
$offset[] = $z->getOffset($c);
$added[] = $zone['timezone_id'];
}
}
}
array_multisort($offset, SORT_ASC, $data);
$options = array();
foreach ($data as $key => $row) {
$options[$row['timezone_id']] = $row['time'] . ' - '
. formatOffset($row['offset'])
. ' ' . $row['timezone_id'];
}
// now you can use $options;
function formatOffset($offset) {
$hours = $offset / 3600;
$remainder = $offset % 3600;
$sign = $hours > 0 ? '+' : '-';
$hour = (int) abs($hours);
$minutes = (int) abs($remainder / 60);
if ($hour == 0 AND $minutes == 0) {
$sign = ' ';
}
return 'GMT' . $sign . str_pad($hour, 2, '0', STR_PAD_LEFT)
.':'. str_pad($minutes,2, '0');
}
When I checked my country, the offset was wrong, I am in Asia/Singapore, it should be UTC/GMT +8 http://www.timeanddate.com/worldclock/city.html?n=236 but according to the generated list its +9. Is there some kind of logic error? The time was correct tho
Is there a better way to generate this list? from the same question in the link above,
static $regions = array(
'Africa' => DateTimeZone::AFRICA,
'America' => DateTimeZone::AMERICA,
'Antarctica' => DateTimeZone::ANTARCTICA,
'Aisa' => DateTimeZone::ASIA,
'Atlantic' => DateTimeZone::ATLANTIC,
'Europe' => DateTimeZone::EUROPE,
'Indian' => DateTimeZone::INDIAN,
'Pacific' => DateTimeZone::PACIFIC
);
foreach ($regions as $name => $mask) {
$tzlist[] = DateTimeZone::listIdentifiers($mask);
}
This just gets the identifiers I want a friendly display name eg. UTC+8 Asia/Singapore or something similar. How can I get that?

The below outputs the HTML <option>'s with all timezones specified in the $desiredRegions array.
function getAllTimeZones(){
$zoneIdentifiers = timezone_identifiers_list();
$zoneLocations = array();
foreach ($zoneIdentifiers as $zoneIdentifier)
{
$zone = explode('/', $zoneIdentifier);
$desiredRegions = array(
'Africa', 'America', 'Antarctica', 'Arctic', 'Asia', 'Atlantic', 'Australia', 'Europe', 'Indian', 'Pacific'
);
if (in_array($zone[0], $desiredRegions))
{
if (isset($zone[1]) != '')
{
$area = str_replace('_', ' ', $zone[1]);
if (!empty($zone[2]))
{
$area = $area . ' (' . str_replace('_', ' ', $zone[2]) . ')';
}
$zoneLocations[$zone[0]][$zoneIdentifier] = $zone[0] . '/' . $area;
}
}
}
$selectOptions = "";
foreach($zoneLocations as $zoneRegion => $regionAreas)
{
foreach($regionAreas as $regionArea => $zoneLabel)
{
$currentTimeInZone = new DateTime("now", new DateTimeZone($regionArea));
$currentTimeDiff = $currentTimeInZone->format('P');
$selectOptions .= "<option value=\"$regionArea\">(GMT $currentTimeDiff) $zoneLabel</option>\n";
}
}
return $selectOptions;
}
echo getAllTimeZones();
Output would look like:
<optgroup label="Africa">
<option value="Africa/Abidjan">(GMT +00:00) Africa/Abidjan</option>
<option value="Africa/Accra">(GMT +00:00) Africa/Accra</option>
<option value="Africa/Addis_Ababa">(GMT +03:00) Africa/Addis Ababa</option>
[...]
</optgroup>
Based on this gist.

I would like to leave here this idea:
/*----------TIME ZONE LIST---------*/
function TZList($data_type = false){
$_all_timezone_identifiers = DateTimeZone::listIdentifiers(DateTimeZone::ALL);
$TIMEZONE_LIST = array();
foreach($_all_timezone_identifiers as $k => $v){
$_tzone_group = explode("/", $_all_timezone_identifiers[$k])[0];
$_tzone_new = new DateTimeZone($_all_timezone_identifiers[$k]);
$_tzone_new_date = new DateTime("now", $_tzone_new);
$tzone_arr = array(
'timezone' => $_all_timezone_identifiers[$k],
'timediff' => $_tzone_new_date->format('P'),
'timezone_offset' => $_tzone_new_date->format('Z')/60, //minutes
'text' => "(GMT" .$_tzone_new_date->format('P') .") " .$_all_timezone_identifiers[$k]
);
//BY CONTINENT
if($data_type === true) $TIMEZONE_LIST[$_tzone_group][] = $tzone_arr; else $TIMEZONE_LIST[] = $tzone_arr;
}
//BY TIMEZONE: "America/New_York"
if(is_string($data_type)){
$key = array_search($data_type, array_column($TIMEZONE_LIST, 'timezone'));
$TIMEZONE_LIST = $key !== false ? $TIMEZONE_LIST[$key] : null;
}
return $TIMEZONE_LIST;
}
/*--------------------------------*/
Thank you.

if you are looking to generate a similar timezone list as give in the image below
You can use the following php code to generate the dropdown list using the DateTimeZone::listIdentifiers -- timezone_identifiers_list — Returns a numerically indexed array containing all defined timezone identifiers.If you want a list of ALL possible values (including backwards compatible aliases), use DateTimeZone::ALL_WITH_BC in place of DateTimeZone::ALL
echo "<select>";
$tzlist = DateTimeZone::listIdentifiers(DateTimeZone::ALL);
foreach($tzlist as $value)
{
echo "<option value=". $value .">". $value ."</option>";
}
echo "<select>";

This is the solution that I find better than a hardcoded array, because offsets are calculated dynamically.
<?php
function toGmtOffset($timezone){
$userTimeZone = new DateTimeZone($timezone);
$offset = $userTimeZone->getOffset(new DateTime("now",new DateTimeZone('GMT'))); // Offset in seconds
$seconds = abs($offset);
$sign = $offset > 0 ? '+' : '-';
$hours = floor($seconds / 3600);
$mins = floor($seconds / 60 % 60);
$secs = floor($seconds % 60);
return sprintf("(GMT$sign%02d:%02d)", $hours, $mins, $secs);
}
$timezones = array(

I used both lists from Jiew Meng and Tamás Pap, for each I checked PHP support of timezone identifier (PHP supports less than world knows), and made a composite list. For those Timezones which were in both lists and had support by PHP but had different identifiers I selected ones that are used in Geonames cities DB. Result is below:
$timezones = Array(

Try the following code from How do I get Greenwich Mean Time in PHP?. I use it on one of my apps, but you can change the markup to display whatever you want:
public function tz_list() {
$zones_array = array();
$timestamp = time();
foreach(timezone_identifiers_list() as $key => $zone) {
date_default_timezone_set($zone);
$zones_array[$key]['zone'] = $zone;
$zones_array[$key]['offset'] = (int) ((int) date('O', $timestamp))/100;
$zones_array[$key]['diff_from_GMT'] = 'UTC/GMT ' . date('P', $timestamp);
}
return $zones_array;
}
Then:
<select name="timezone" id="timezone" class="form-control">
<option value="">Select a time zone</option>
<?php foreach(tz_list() as $t) { ?>
<option value="<?php echo $t['offset']; ?>___<?php echo $t['zone']; ?>"
<?php echo $t['diff_from_GMT'] . ' - ' . $t['zone']; ?></option>
<?php } ?>
</select>

It is very important to store timezone identifiers in your database and not just the timezone offset like "GMT+2", because of Daylight Saving Times.

I have just had the same problem of making an easy to use time zone list. So I am using geoip (http://freegeoip.net) to get the user's country and then using:
$nearest_time_zones = DateTimeZone::listIdentifiers(DateTimeZone::PER_COUNTRY, $country_code);
This is great because the list is generally very short. But in case the user wants to specify a different zone I append the entire list from DateTimeZone::listIdentifiers(). If you don't show all time zones, you're bound to have a user from a time zone that isn't listed.
The resulting drop down looks like this (of course it's a lot longer than this):
<optgroup label="Nearest">
<option value="blah/blah">(+5:00) Blah/Blah</option>
...
</optgroup>
<optgroup label="-11:00">
<option value="Pacific/Apia">(-11:00) Pacific/Apia</option>
<option value="Pacific/Midway">(-11:00) Pacific/Midway</option>
<option value="Pacific/Niue">(-11:00) Pacific/Niue</option>
<option value="Pacific/Pago_Pago">(-11:00) Pacific/Pago_Pago</option>
</optgroup>
<optgroup label="-10:00">
<option value="America/Adak">(-10:00) America/Adak</option>
<option value="Pacific/Fakaofo">(-10:00) Pacific/Fakaofo</option>
<option value="Pacific/Honolulu">(-10:00) Pacific/Honolulu</option>
<option value="Pacific/Johnston">(-10:00) Pacific/Johnston</option>
<option value="Pacific/Rarotonga">(-10:00) Pacific/Rarotonga</option>
<option value="Pacific/Tahiti">(-10:00) Pacific/Tahiti</option>
</optgroup>
This application is still in development and hasn't had user feedback yet so I can't say that this has been a successful approach. But I thought that the geoip approach was worth mentioning.

this method relies on your operating system, to make it so that it always works, just store the excisting timezones in an array/database, also you need to take into account the daylightsavingstime(s) wich can be quite some work
sourece http://en.wikipedia.org/wiki/Time_zone: PHP
The DateTime objects and related functions have been compiled into the PHP core since 5.2. This includes the ability to get and set the default script timezone, and DateTime is aware of its own timezone internally. PHP.net provides extensive documentation on this.[20] As noted there, the most current timezone database can be implemented via the PECL timezonedb.
so either make the db yourself, or use the PECL timezonedb
