PHP code to get timezone from latitude and longitude

It is as simple as taking your latitude and longitude from your location and calling geonames.org webservice using the code below

Enjoy.

Update: sorry, "<" was not replaced by "& lt;" and neither did ">" by "& gt;"

$latitude = .....

$longitude = .....

$geonames_call ="http://ws.geonames.org/timezone?lat=" . $latitude . "&lng=" . $longitude;

$output = file_get_contents( $geonames_call );

preg_match("/<timezoneId>(.*?)<\/timezoneId>/ims", $output, $matches);

$timezone = $matches[1];

echo "Timezone = ", $timezone, "<br/>
";

PHP code for reverse geocoding

"Geocoding is the process of converting addresses (like "1600 Amphitheatre Parkway, Mountain View, CA") into geographic coordinates (like latitude 37.423021 and longitude -122.083739), which you can use to place markers or position the map. The Google Geocoding API provides a direct way to access a geocoder via an HTTP request. Additionally, the service allows you to perform the converse operation (turning coordinates into addresses); this process is known as "reverse geocoding." "
from http://code.google.com/apis/maps/documentation/geocoding/


Below you can find the PHP code (written by myself) to get the different properties of an address, given the latitude and longitude


Enjoy.
