fsocketopen not returning data properly

I'm having trouble with sockets in PHP, if anyone has the time to help out that would be awesome. I am trying to get the result of a post echo httpSocketConnection("www.google.com", "POST", "/search", "q=test", "80"); This should post to google.com with a query of test. Then give me the response. The function I'm using is below. Here's the function's code: function httpSocketConnection($host, $method, $path, $data, $port) {

       $method = strtoupper($method);

       if ($method == "GET")
       {
           $path.= '?'.$data;
       }

       $filePointer = fsockopen($host, $port, $errorNumber, $errorString);

       if (!$filePointer)
       {
           logEvent('debug', 'Failed opening http socket connection: '.$errorString.' ('.$errorNumber.')<br/>\n');
           return false;
       }

       $requestHeader = $method." ".$path."  HTTP/1.1\r\n";
       $requestHeader.= "Host: ".$host."\r\n";
       $requestHeader.= "User-Agent:      Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0\r\n";
       $requestHeader.= "Content-Type: application/x-www-form-urlencoded\r\n";

       if ($method == "POST")
       {
           $requestHeader.= "Content-Length: ".strlen($data)."\r\n";
       }

       $requestHeader.= "Connection: close\r\n\r\n";

       if ($method == "POST")
       {
           $requestHeader.= $data;
       }

       fwrite($filePointer, $requestHeader);

       $responseHeader = '';
       $responseContent = '';

       do
       {
           $responseHeader.= fread($filePointer, 1);
       }
       while (!preg_match('/\\r\\n\\r\\n$/', $responseHeader));

       if (!strstr($responseHeader, "Transfer-Encoding: chunked"))
       {
           while (!feof($filePointer))
           {
               $responseContent.= fgets($filePointer, 128);
           }
       }
       else
       {

           while ($chunk_length = hexdec(fgets($filePointer)))
           {
               $responseContentChunk = '';

               logEventToTextFile('debug', $chunk_length);
               $read_length = 0;

               while ($read_length < $chunk_length)
               {
                   $responseContentChunk .= fread($filePointer, $chunk_length - $read_length);
                   $read_length = strlen($responseContentChunk);
               }

               $responseContent.= $responseContentChunk;

               fgets($filePointer);

           }

       }

       logEventToTextFile('debug', $responseContent);

       return chop($responseContent);
   }
