Question

Is’t possible to get list of all session_id in PHP SESSIONS?

Note:
I need maintained some file in the server. One file equal one session. And I need to determine behaviour of old files if SESSION expire.

Thank you all for any advice.

Answer 1

i’d to do this in an old project.

i named the files with the session_id (something like this: sessionid_some_file.tmp) :

_TMP_PATH_ : path where the files to check are.

foreach(new DirectoryIterator(_TMP_PATH_) as $file)
{
    if(preg_match('/(.*)_(.*)_(.*)\.tmp/', $file->getFilename(), $data))
    {
        session_write_close();
        $session_id = $data[1];
        session_id($session_id);
        session_start();
        if(empty($_SESSION))
        {
            unlink(_TMP_PATH_ . $file->getFilename()); 
        }
    }
}
session_write_close();

foreach files i get the session_id, open it and test if something inside. (i wrote something after each session opened)

But be carefull, this piece of code has never been in a production environnment.
