[PHP-DB] php sessions
Hi! I have a few questions about the sessions in php. I have a website where users are authentified through a login/password stored in a database. Once accepted, I start a session. - can I "disconnect" an user? I mean I have a logout script, which is called when the user wants to logout, but can I log him out myself? I was thinking deleting the session files in php/tmp, but I don't have this access (and don't think it is a good way). My second idea was logging myself as this user (as I know the login/pass), but will this end its session? I am not recoding the logout in the sql tables, so is there any way for me to kno which sessions are still active? - this lead to my second question, can I limit the number of session per user (to 1)? I think it is possible, because I saw on some websites the warning "only one active session allowed per user, if you are already logged in you will be disconnected" but I don't know how this is managed. - if my user is logged in (active session) and try to re-log in, will he open a new session or will he re-use the already opened one? I think the global idea behind all this is how to attach a session to an user and how to control it. Thanks for your help! _ Want to block unwanted pop-ups?

RE: [PHP-DB] Cannot connect to local server
Thanks, Miles!
But actually I have PHP 5.0.2 + MySQL 4.1.9 + mysqli + PEAR::DB latest
installed on the server.
I have spent some weeks struggling with connection and charset problems. But
today I finally solved all these issues except one thing that seems to be a
bug of PEAR::DB package.
The problem is that I CAN connect using
mysqli://user:[EMAIL PROTECTED]/dbname
connection string and CANNOT connect using
mysqli://user:[EMAIL PROTECTED]/dbname
(privileges/passwords ok, don't worry)
In the last case DB still raises the error message saying:
"Can't connect to local MySQL server through socket '' (111)"
(notice '')
Default socket /var/lib/mysql/mysql.sock does exist. Furthermore, I CAN
connect to localhost using mysqli_* functions. But DB package still shows me
errors when connecting to localhost (and all is OK when it is trying to
connect to example.com via TCP/IP).
Dear DB maintainers, should I report a bug?

RE: [PHP-DB] To login a user without grant on ISP mysql
You need an account with at least select privileges to run any query. Are you trying to create an account on the mysql for each user? Don't do that. Use table based authentication for each user and use whatever default mysql account you have to run the queries.

[PHP-DB] referencing external functions
Sorry if this is a duplicate. I accidentally sent to the listserve from
the wrong address.
I am having trouble calling external functions. I am trying to use this
to clean up the code in the display. I have this as the function.php
function links() {
global $link;
$sql = "select * from jozef_links";
$result = mysql_query($sql, $link) or die (mysql_error());
echo "";
while ($array = mysql_fetch_array($result)) {
$id = $array['link_name'];
$url= $array['link_url'];
echo "$id\n";
}
echo "";
}
?>
and am trying to use it in this links3.php
but I keep getting the error message
*Warning*: main(1): failed to open stream: No such file or directory in
*C:\Accounts\dbadream\wwwRoot\links3.php* on line *4*
*Warning*: main(): Failed opening '1' for inclusion
(include_path='.;c:\php4\pear') in
*C:\Accounts\dbadream\wwwRoot\links3.php* on line *4*
Can anyone explain what is wrong. Both files are in the same directory
and and both have the normal permissions set to access.
Thanks,

try the absolute path and try require_once() instead of include().
Also "or die (mysql_error());" is not going to get you anything. That
is the text of the error message from previous MySQL operation.

RE: [PHP-DB] referencing external functions
the error tells me that the files are not in the same dir...I have run into
this one as well and it was always that case.
Your usage is off though...What you need to do is to include the
functions.php page and then call a particular function..also any error
handling should be with the function itself
I handle mine a little differentlytry this:
//echo "commnecing connection to local db";
if (!($conn=mysql_connect($host, $username, $pwd))) {
printf("error connecting to DB by user = $username and pwd=$pwd");
exit;
}
$db3=mysql_select_db($dbname,$conn) or die("Unable to connect to local
database");
$result = mysql_query($sql) or die ("Can't connect because ".
mysql_error());
return $result;
}//end function
?>
Then I include the function like this
require("conn.php");
$sql = "select * from table";
$result = conn($sql); //runs the query and passes back the result
if ($result){
//do something here
}
?>
In your case...i changed your code somewhat
function links() {
//global $link;
$sql = "select * from jozef_links";
$link = connect(); //call the connect function to create the link
$result = mysql_query($sql, $link) or die (mysql_error());
echo "";
while ($array = mysql_fetch_array($result)) {
$id = $array['link_name'];
$url= $array['link_url'];
echo "$id\n";
}
echo "";
}
?>

RE: [PHP-DB] php sessions
The only way to be able to track user sessions would be to use a db, for the functionality that you want. Move your entire sessoion handling to the db (see here for an article on this:http://www.phpbuilder.com/columns/ying2602.php3?aid=19 ) You can track user ids, session ids, ip addresses etc with a table. Then its a simple matter to kill a user session by flagging or deleting the record. Sessions tracking and limiting can be done in two ways: 1. use a cookie and check for the existance of this cookie when the user attempts to log on 2. store the IP in a session variable Bastien From: "mel list_php" <[EMAIL PROTECTED]> To: php-db@lists.php.net Subject: [PHP-DB] php sessions Date: Tue, 15 Feb 2005 09:49:24 + Hi!

Re: [PHP-DB] referencing external functions
You can have that happen even with this code. If they limit the max_connections, then the only thing you can do is to manage the connections the best you can. OPen and close then for the bare minimum time. Create the SQL, then open the connection, process it, get the resultback and close the link. bastien From: "J.

[PHP-DB] Database visible via mysql CLI but not MOD_PHP with same username
I have encountered a "hidden database" issue with mod_php, apache2 and mySQL that I have thus far been unable to resolve. I am able to connect to the mysql socket using mysql_connect, but then find that mysql_list_dbs only returns the "test" database. This *sounded* like an issue with the SHOW DATABASES privilege until I found I was able to log in to the same MySQL server *as the same user* with the provided command-line client (mysql) and SHOW DATABASES would display all the other databases on this system. Furthermore, I tried connecting as root, and again found only the "test" database was visible to PHP. If I dropped the test database, no databases were visible to PHP (regardless of how many databases were visible using SHOW DATABASES). If I created "test", "tester", "testing", "hello" etc, then the "test" database would reappear to PHP, but no other databases were visible. I also tried to connect PHP to MySQL as a super-user, and encountered the exact same issue. Any advice appreciated, M. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] php sessions
you could put in a database an action field, and have a function check the action on every page. If the action says certain things, like KILL or REVALIDATE, then have it perform certain actions. For the first, I'd output an error page that says something like "Your session was killed by administrator (Admin ID)." Or, ask them for their password before carrying out their request for the latter example. there are several ways to do this. It all depends on what your server's capabilities and resources are (databases and such) and personal preference. HTH, -- The Disguised Jedi [EMAIL PROTECTED] Now you have my $0.02.
