使用php发送GET请求时出现HTTP 400 BAD REQUEST错误

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...
        $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?

    For this specific problem I've found a solution. If you want to get the headers from the request that I sent in the question above, you can use php's get_headers($url) method. It retrieves the headers that I was looking for. I'm really new to protocols and web-services and also to php (1 or 1.5 weeks), therefore I may have asked a silly question and not have been specific enough. Anyways thank you very much for your answers.

    Have a nice day!

    A GET request also contains a header wich include things like the useragent oder the encoding, you should have a look at what you need to send and what's optional
