This is a quick example of one way to grab the full region name based on country and region code provided by the php geoip module using MaxMind's region.csv for the data.

region.csv

region.php

<?php

function getFullRegionName($geo)
{
  $regionName = "Unknown";
	
	if (($handle = fopen("region.csv", "r")) !== FALSE)
	{
	    while (($data = fgetcsv($handle, 256, ",")) !== FALSE)
		{
			if($data[0] == $geo['country_code'] && $data[1] == $geo['region'])
			{
				$regionName = $data[2];
				break;
			}
	    }

	    fclose($handle);
		
		return $regionName;
	}
	
	return "Error Opening region.csv";
}

?>

test.php

<?php

include('region.php');

echo getFullRegionName(geoip_record_by_name($_SERVER['REMOTE_ADDR']));

?>
