Need Help with PHP REGEX

Hello, I have this script:
Code:
<?php

function getLocation() {
$ip = $_SERVER['REMOTE_ADDR'];
$geo = file_get_contents("http://api.hostip.info/get_html.php?ip=$ip");
$results = urlencode($geo);
echo $results;
}

getLocation();

?>

Which returns:
Code:
Country%3A+CANADA+%28CA%29%0ACity%3A+ST.+JOHN%27S%2C+NL%0AIP%3A+142.162.13.207%0A

I would like for $results to contain only "ST.+JOHN%27S%2C+NL"; in other words the city name and the province/state for the visiting user.

What I'm aiming to do is make the regex change after this line:
Code:
$geo = file_get_contents("http://api.hostip.info/get_html.php?ip=$ip");

and before this line:
Code:
$results = urlencode($geo);

This way the modified data (ie. "City%2C+State") gets passed off into $results.
I need $results encoded because this script is going to be part of another script where $results get passed off as part of a URL parameter.

Regex seems to work differently with PHP, and I don't have much experience with regex or arrays; I'm just learning as I go Smilie
Any help would be greatly appreciated. Thanks Smilie
