Answer 1

    /* gets the data from a URL */
    function get_data($url) {
        $ch = curl_init();
        $timeout = 5;
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
        $data = curl_exec($ch);
        curl_close($ch);
        return $data;
    }
$strDetails = get_data("http://www.dndstatus.com/dnd-check-process.php?num=9721395967");

Alternatively, you can use the file_get_contents function remotely, but many hosts don't allow this.
