Hi,
I am using fsockopen to simulate a POST to another page (test_post.php) within
the same server.
Data sent to the socket is:
"POST $uri HTTP/1.1\r\n".
"Host: $host\n". "User-Agent: mandapost\r\n".
"Cookie: ".session_name()."=". session_id()."\r\n".
"Content-Type: application/x-www-form-urlencoded\r\n".
"Content-Length: $contentlength\r\n".
"Connection: close\r\n\r\n".
"$my_post_variables\r\n";
$_SESSION is used to hold some variables.
test_post.php is:
<?php
session_start();
echo "User".$_SESSION["user"];
...
The problem is that session_start creates a new session instead of using the
session_id indicated in the cookie.
A user comment in the online PHP manual says:
"Just for info, session_start() blocks if another PHP using the same session
is still running in background. It seems it's waiting the other PHP to
finish... and sometimes it can be a problem. Create 2 different sessions by
setting 2 different names : session_name() solve the problem."
The above comment seems correct and PHP hangs until some time-out or something
occurs. The previous session is not started anyway.
I tried to change the name with use session_name, to change the ID with
session_regenerate_id, also some tests with session_id, ...
I also tried to send data to the sockect using PHPSESSID and $_COOKIE instead
of session_name and session_id.
This is my current code:
<?php
$previous_name = session_name("MASIVO");
//sessionid($previous_name);
session_start();
//session_regenerate_id();
echo "##".$previous_name."##".$_COOKIE[$previous_name]."##"; // (1)
echo "User".$_SESSION["user"];
(1) It is correct: ##PHPSESSID##09a169b69eccbf2dd49407c5d4cc84aa##
And this is what the socket returns:
HTTP/1.1 200 OK Date: Mon, 07 Mar 2005 13:43:51 GMT Server: Apache/1.3.28
(Unix) PHP/4.3.3 mod_ssl/2.8.15 OpenSSL/0.9.7c X-Powered-By: PHP/4.3.3

Pedro.
