Sessions Management PHP Class 1.0.1
Monday, September 11, 2006News, Sessions Management PHP Class
A new version of the Sessions Management PHP Class has been released. Read further to see what is new in this version of the script.
What's new in this version:
- in the 'session_data' table, the 'session_id' field is now a primary key and it's type is changed from varchar(255) to varchar(32). previously a whole table scan was done every time a session was loaded - thanks Harry
- added a new "stop()" method which unsets a session's variables and deletes it from the database. this is due to the fact that some people were using the private "destroy" method which is not to use for this purpose
- you can now override the default settings of session.gc_maxlifetime, session.gc_probability and session.gc_divisor configuration options
- on popular request, an example file was added

Hi
I've tried your class but i've got a question: how can you do to recover data in the session_data row?
I've create a function to get all connected user in my website and i want to get the data from session_data.
For ex:
$_SESSION[page][var1]='test';
$_SESSION[page][var2]='test2';
...
I've tried with an unserialize and also with session_decode but no way...
Can you help me?

so many people got it all wrong! and you are one of them :)
as the documentation says: "after instantiating the class, use sessions as you would normally"
everything is ok with adding data to the session as you described here:
$_SESSION[page][var1]='test';
$_SESSION[page][var2]='test2';
that would put the data in the session. you have to ignore the fact that the data is stored in a database. that's transparent to you. you just use sessions as you would normally.
With
$_SESSION[page][var1]='test';
$_SESSION[page][var2]='test2';
you add the data to your session.
Now go ahead and print_r($_SESSION) and you'll see that the data is in the session. Try and print_r($_SESSION[page][var1]) and you'll get 'test'!

this is not the problem, the problem is to get all data from all user on the website, it is not possible to get $_SESSION from an other visitor than me.
I've find the solution with this code:
function unserializesession($data) {
$vars=preg_split('/([a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*)\|/',$data,-1,PREG_SPLIT_NO_EMPTY | PREG_SPLIT_DELIM_CAPTURE);
for($i=0; $vars[$i]; $i++)
{
$result[$vars[$i++]]=unserialize($vars[$i]);
}
return $result;
}

oh, i understand. yeah, i found the code too in the php manual but does it work if the SESSION data contains the "|" character?
