problem reading fsockopen stream

[jogisarge]

hello,

 

i have a problem with fsockopen.

i send a xml-file to webserver and wait for the answer.

 

$fp = fsockopen("ssl://server.com",443,$errstr,$errno);
if(!$fp)
{
    die();
}
else
{ 
    $file = addslashes($file);
    $data = $file;
    fputs($fp, "POST /webservice/XMLServlet HTTP/1.0\r\n");
    fputs($fp, "Host: server.com\r\n");
    fputs($fp, "Authorization: Basic ".$kennung." \r\n");
    fputs($fp, "Content-length: ". strlen($data) ."\r\n");
    fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
    fputs($fp, "Connection: close\r\n\r\n");
    fputs($fp, $data);
}
$xxx = 1;
while(!feof($fp))
{ 
    echo "Step ".$xxx." : ".date("d.m.Y - H:i:s")."<br>\n";
    $data .= fgets($fp, 2048);
    $xxx++;
}

the script is very slow.

so i debug with timesteps.

i call the script 4 times in a minute and the time between Step 1 and two is different.

at the end (call4) the response is very fast.

can anybody tell me, why the first fgets is so slow, and why the fgets is getting faster in the other calls ?

 

bye jogi

It could be that the file you are sending is large and a) your upstream speed is slow or b) the servers downstream speed is slow.
