hello

i want to be able to send a packet to a http server and receive the
response, but i'm not quite sure how to do it. i thought of using
sockets, and although i have worked out how to send data to the http
server, i have no idea how to receive the responses.

any help wuld be greatly appreciated.

this is what i've got so far. i know that the server is receiving the
data because i have employed this technique before, only previously i
did not need to receive the response.

<?php

function login()
{
$data = "POST /admin/default.asp HTTP/1.1\r\n";
$data .= etc etc etc

$socket = socket_create(AF_INET,SOCK_STREAM,SOL_TC
P);
$connection = socket_connect($socket,'(*IP ADDRESS*)','80');

socket_write($socket,$data);
socket_close($socket);
}

login();

?>

Avoid using HTTP 1.1 - in my experience, PHP4 doesn't handle the chunked
transfer encoding very well. I don't know if they have sorted this out in
later versions though. The examples you are looking for are here:

Take a look at the php manual item about fsockopen() at www.php.net .
There are examples too.

It is like reading and writing files with fread fgets.

Anyway, to not reinvent the wheel you may want to try this http client
class that supports posting forms, redirection, collecting cookies, etc..
