Web WhoAmI

Your IP address is 54.159.51.118
Your location is Unknown (--)

You are probably familiar with the WHOAMI command.
This is a web version of that command

PHP Code:

<?php
$ip     = $_SERVER['REMOTE_ADDR'];
$xmlstr = file_get_contents( "http://www.webservicex.net/geoipservice.asmx/GetGeoIP?IPAddress={$ip}" );
$xml    = new SimpleXMLElement( $xmlstr );
$rc     = $xml->ReturnCode[0];
if ( $rc == 1 ) {
    $countryname = ucwords( strtolower( $xml->CountryName[0] ) );
    $countrycode = $xml->CountryCode[0];
} else {
    $countryname = 'Unknown';
    $countrycode = '--';
}
print "<p>Your IP address is {$ip}<br>\n Your location is {$countryname} ({$countrycode})</p>";
?>

As you can see in the code, it is based on webservicex.net's GetGeoIP functionality.

Note: A note from Stan Littlefield: for local use, replace $ip = $_SERVER['REMOTE_ADDR']; by $ip = file_get_contents('http://whatismyip.org/');
