While I'm trying to send a GET request to an address with php I receive HTTP 400 BAD REQUEST message and I can't figure out why.

Here's my code:

function redirect($url)
{
    error_reporting(E_ERROR | E_PARSE);

    $components = parse_url($url);

    $port = $components["port"];
    $ip = $components["host"];
    $path = $components["path"];

    //create and connect socket with the parameters entered by the user
    //$sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP);

    echo "Establishing connection to the given adress...
";


    //Connection timeout limit is set to 10 seconds...
    if(!isset($port))
    {
        $port = 80;
    }
    $sock = fsockopen($ip, $port,$errno, $errstr, 10) or die("Unable to connect...");

    $request = "GET $path HTTP/1.1" . "

";


    fwrite($sock, $request);

    while ($header = stream_get_line($sock, 1024, "
")) {
        $response.= $header . "
";
    }
    echo $response;
    $loc = "";

    if (preg_match("/Location:\'(.*)\
/", $response, $results))
        $loc = $results[1];

    echo $loc;

}

Any suggestions?
