Little coding help

[litewarez]

if you understood functions/methods/classes and how there stored in scope then you would realise that what your doing is wrong!

{php}
function alexaRank($domain){
    $remote_url = 'http://data.alexa.com/data?cli=10&dat=snbamz&url='.trim($domain);
    $search_for = '<POPULARITY URL';
    if ($handle = @fopen($remote_url, "r")) {
        while (!feof($handle)) {
            $part .= fread($handle, 100);
            $pos = strpos($part, $search_for);
            if ($pos === false)
            continue;
            else
            break;
        }
        $part .= fread($handle, 100);
        fclose($handle);
    }
    $str = explode($search_for, $part);
    $str = array_shift(explode('"/>', $str[1]));
    $str = explode('TEXT="', $str);

    return $str[1];
} // CREATE THE FUNCTION INSTANCE OUT OF THE LOOP
{/php}
{foreach from=$linkdetail item=linkdetail}
{php}
echo alexaRank($linkdetail.URL); //not sure if you can pull smarty vars into php blocks
{/php}
