[RESOLVED] it doesn't work in function

[wiz126]

ok My code doesn't work when its in a function, yet it does when its not why is that?

This Works:

$handle = fopen("http://www.runescape.com/lang/en/aff/runescape/serverlist.ws?lores.x=0&plugin=0&order=WPML","r");
if($handle){
while (!feof($handle)) {
$contents .= fread($handle,8192);}
fclose($handle);}

$world = 2;
$lengthA = strpos(stristr($contents, 'World '.$world), 'FULL');
$lengthB = strpos(stristr($contents, 'World '.$world), 'Players');

if ($lengthA < $lengthB){
        echo 'Full';
    }
else
    {
        echo strpos(stristr($contents, 'World '.$world), 'Players');
    } 

And This Doesn't:

$handle = fopen("http://www.runescape.com/lang/en/aff/runescape/serverlist.ws?lores.x=0&plugin=0&order=WPML","r");
if($handle){
while (!feof($handle)) {
$contents .= fread($handle,8192);}
fclose($handle);}
   

function Population($world)  {
    $lengthA = strpos(stristr($contents, 'World '.$world), 'FULL');
    $lengthB = strpos(stristr($contents, 'World '.$world), 'Players');
    
    if ($lengthA < $lengthB){
            return "Full";
        }
    else
        {
            return strpos(stristr($contents, 'World '.$world), 'Players');
        }
}
echo Population(2); 

Why is that?
