[PHP] Cookie
Hi, I use : apache 1.3.26, php 4.2.3, postgresql 7.2 (under solaris 7). I attempt to modify my old sources which run with the previous versions and I meet a problem with the cookie. I read that we can see the contents of a cookie with 2 methods : echo $testcookie echo $_COOKIE["testcookie"] For me, only the second method runs. An idea ?

Re: [PHP] Cookie
Thanks for your response. The doc isn't explicit when it explains this two methods and don't focus on the register globals function for the first method. So I use the second method only.

[PHP] Erase the cookie sessions
Hi, I wish test the session. I use php 4.2.3 et session.auto_start is 1. My first example is : Session example "; echo "hello ! : $cpt times"; session_unset(); session_destroy(); } ?> I don't find the solution to use setcookie ; I try the two instructions above (the script is correct without the "else"). An idea ? In advance, thanks. mb -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Solved : my solution for information (before test with url !)
5 )
{
$cook_param= session_get_cookie_params();
$life_time= $cook_param['lifetime'];
$path= $cook_param['path'];
setcookie(session_name(),"",$life_time,$path);
echo "Session and cookie";
echo "session change";
echo "hello ! : it's ".$_SESSION['count']."times and the last";
$_SESSION= array();//session_unset();
session_destroy();
echo "";
}
else
{
echo "Session and cookie";
$cpt = $_SESSION['count'];
echo "hello ! : it's ".$_SESSION['count']."times";
echo " Information :";
echo "name = ".session_name()."";
echo "id = ".session_id()."";
echo "";
}
?>
The problem was setcookie execution after the header sending.

[PHP] Session and URL
I meet a probleme with the session.
My example considers 2 scripts :
- the first script (test_session_url.php) opens a session
(session.auto_start=1 in php.ini), defines a counter,
prints some information and an hypertext to execute the second script
which
has session id as parameter
Session and URL";
echo "hello ! : it's ".$_SESSION['count']." visit";
echo " Information :";
echo "--->name = ".session_name()."";
echo "--->id = ".session_id()."";
echo "next page";
echo "";
?>
- the second script (nextpage_session_url.php) validates the parameter
(set, empty, value), add one to the counter and then check the value of
the counter. It makes the same thing
5 times by printing an hypertext with itself and after, it prints an new
hypertext to come back to the first script by beginning a NEW SESSION.
Session and URL";
echo "parameter error";
echo "";
exit;
}
$id= $_GET[session_name()];
if ( $id != session_id() )
{
echo "Session and URL";
echo "value of session id error : ";
echo "parameter : $id and current session_id :".session_id()."--";
echo "";
}
else
{
$_SESSION['count']++;
if ( $_SESSION['count'] > 5 )
{
$_SESSION= array();
session_destroy();
session_start(); // problem is the same with or without this
instruction
include("test_session_url.php");
}
else
{
echo "Session and URL";
$cpt = $_SESSION['count'];
echo "hello ! : it's ".$_SESSION['count']." visit";
echo " Information :";
echo "--->name = ".session_name()."";
echo "--->id = ".session_id()."";
echo "next page";
echo "";
}
}
?>
Now my problem : NEVER a new session (with a new ident) is created.
However I execute $_SESSION= array(); and session_destroy();
I use php 4.2.3 and apache 1.3.26
For testing, I configurate my browser to refuse the cookies (but the
problem
is the same when I accept the cookies).
Perhaps something to change in php.ini ?
In advance thanks.

Re: [PHP] Sessions: Trigger a new one, Expire an old one
Hi,
I use php 4.2.3 with session.auto_start = 1 in php.ini
What I use with URL session :
$_SESSION= array();
unset($_GET[session_name()]);
session_destroy();
Header("Location: next_script.php");
with cookie session :
$cook_param= session_get_cookie_params();
$life_time= $cook_param['lifetime'];
$path= $cook_param['path'];
setcookie(session_name(),"",$life_time,$path);
$_SESSION= array();
session_destroy();

[PHP] Postgres-Transaction-user_ignore_abort-Connection stop by the client
Hi,
I use Postgresql 7.2.2 + php 4.2.3 and I meet a problem with
transaction and connections interruption.
The application is the famous example of the bank accounts and the money
transfers. I consider a table named "DEAL" where each transaction is
saved. Each tuple has an id number as key. When a tuple is added,
the maximum value of id is computed, and increased by one to
determinate the key of the next tuple.
My script php follows this steps :
ignore_user_abort(0|1)
Compute the key -> v
BEGIN WORK
UPDATE the first bank account with v (credit)
sleep(300)
UPDATE the second bank account with v+1 (debit)
COMMIT WORK
While the sleep, the client may use the STOP button on his browser and
stop the connection.
I tried to execute exhaustive tests : ignore_user_abort(0) or
ignore_user_abort(1), with or without transaction, with or
without rollback.
For these tests, I follow two steps :
1/ the client execute the first request but stops the connection
while the sleep instruction.
2/ with pgaccess, I read the content of DEAL
3/ the client executes a new request without interruption
4/ the result is displayed on the browser and checked with pgaccess
TEST 1
request 1
*
ignore_user_abort(0)
Compute the key -> v=10
BEGIN WORK
UPDATE the first bank account with v as key (credit)
sleep(300)--> INTERRUPT
UPDATE the second bank account with v+1 as key (debit)
COMMIT WORK
Result : nothing new in the database (with pgaccess)
request 2
*
ignore_user_abort(0)
Compute the key -> v=10
BEGIN WORK
UPDATE the first bank account with v (credit)
UPDATE the second bank account with v+1 (debit)
COMMIT WORK
Result : the request 1 is executed now ! and while the key
(v=10) is the same, the request 2 fails.
Problem : why the whole first request is taking into account
now ?
TEST 2
The same by removing BEGIN and COMMIT.
The first request : only the first update (before the stop)
is executed
The second request is executed correctly.
Problem : ignore_user_abort is called with 0, so why the execution
of the script for the first request doesn't continue ?
TEST 3 and 4
The tests 3 and 4 reproduce the test 1 and 2 by using
ignore_user_abort(1).
The results are absolutely the same !
TEST 5 and 6
The tests 5 and 6 reproduce the test 1 and 2 by using ROLLBACK
if ( connection_aborted() ) { ROLLBACK WORK; exit } is added
after the sleep.
The results are absolutely the same again !
I find the results very strange, isn't it.
In advance, thanks for your help.
