Hi, I have the following code at the moment:

$ip = '195.72.186.157';

$xmlDoc = new DOMDocument();
$xmlDoc->loadXML(file_get_contents('http://www.geoffmeierhans.com/services/geo-locator/locate/?ip='.$ip.'&output=xml'));

foreach($xmlDoc->getElementsByTagName('city') as $link) {
    $links = array('text' => $link->nodeValue);
} 
$city = $links['text'];
echo $city;

Is there a better way to get the city variable? Since there is only one tag called city a loop isn't really needed but I can't get it to work any other way
