Description:
------------
---
From manual page: http://www.php.net/function.geoip-country-code-by-name
---

On development environment, with E_NOTICE enabled, this function will throw an uncatchable and undocumented notice if it can't find the ip, which might break layouts or protocols.

=== Suggestion ===

Remove the notice, the function already inform you it couldn't find the IP by returning false.

=== Workaround ===

Add @ before the function name, disabling any error messages it might throw.

Test script:
---------------
<?php

$name = geoip_country_code_by_name("127.0.0.1");

header("Content-type: application/json");

if ($name) {
    echo json_encode(array( "name"  => $name ));
} else {
    echo json_encode(array( "error"  => "Not Found" ));
}

?>

Expected result:
----------------
A json-encoded response like this:
{ error : "Not Found" }

Actual result:
--------------
<b>Notice</b>:  geoip_country_code_by_name(): Host 127.0.0.1 not found in <b>/path/to/file.php</b> on line <b>3</b><br />
{ error : "Not Found" }
