"Failed to parse address error" please help

[worldcomingtoanend]

after I run my long code I get another error on this function below  "failed to parse address" .  Is my snytax okay or is there anything that u can spot in my code that needs changing. Thank you for help.

 

function sendRequest ($request,$host,$port) {
    // +++++++ connection //
    $socket = fsockopen($host, $port, $errno, $errstr);
    if (!$socket) {
        die("<br>$errno - $errstr<br>");
    }
    // +++++++ Request  //
    $httpRequestLine = "post /xml http/1.1\n";
    $httpHeader = "content-length: ";
    $contentLength = strlen($request);
    $httpRequest = $httpRequestLine . $httpHeader . $contentLength . "\n\n" . $request;
    fputs($socket, $httpRequest, strlen($httpRequest));
    // +++++++ read answer //
    $response = "";
    $line = "";
    while (1) {
          $character = fgetc($socket);
          if ($character == "\n") {
              break;
          } else {
              $line .= $character;
          }
    }
    $requestLineElements = explode(" ",$line);
