WorldTimeEngine – How about making your own in PHP?

I recently came by this site WorldTimeEngine where users can search the local time of any place using the name, street address or just latitude and longitude. Since that time I was thinking how easily you can make your own. As long there are some good people over there (For Geocoding API) – its a not a big deal, you know? Lets have a look at the following PHP code.


<?
$place = "Bucharest";

$geodata = getGeoCode($place);
print_r($geodata);
echo getTime($geodata['lat'],$geodata['lng']);

function getTime($lat, $lng)
{
$url = "http://ws.geonames.org/timezone?lat={$lat}&lng={$lng}";
$timedata = file_get_contents($url);
$sxml = simplexml_load_string($timedata);
return $sxml->timezone->time;
}
function getGeoCode($address)
{
$_url = 'http://api.local.yahoo.com/MapsService/V1/geocode';
$_url .= sprintf('?appid=%s&location=%s',"orchid_geocode",rawurlencode($address));
$_result = false;
if($_result = file_get_contents($_url)) {
preg_match('!<Latitude>(.*)</Latitude><Longitude>(.*)</Longitude>!U', $_result, $_match);
$lng = $_match[2];
$lat = $_match[1];
return array("lat"=>$lat,"lng"=>$lng,"address"=>$address);
}
else
return false;
}
?>


Changing the variable “$place” to “Bucharest”,”Dhaka”, “Toronto” and “Oslo” gives me the following result


Array
(
[lat] => 44.434200
[lng] => 26.102955
[address] => Bucharest
)
2008-03-01 08:41

Array
(
[lat] => 23.709801
[lng] => 90.407112
[address] => Dhaka
)
2008-03-01 12:42

Array
(
[lat] => 43.648565
[lng] => -79.385329
[address] => Toronto
)
2008-03-01 01:42

Array
(
[lat] => 59.912280
[lng] => 10.749980
[address] => Oslo
)

Nice, Huh?
