[PHP] Re: mediator between PHP and Perl (with sessions)
It's quite easy to pass the session variables to the script. The problem with sessions and shell PHP scripts, is that PHP doesn't support sessions on that mode (CLI mode it is called). So, I would have to manualy read the session file and parse it. If anyone knows what is the exact function that is used to unserialize the session file, please tell.. and it's not the unserialize() function in PHP. I guess that using a shell PHP script with sessions is not the solution. Is anybody familiar with another way to use sessions??? but not through web, since the script returns sensitive data. -thanks, Eli -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I THINK you MIGHT be able to use some session functions to set the session
name and session file when you do session_start() and get PHP to do all
the work of the reading/writing the files. You just need to pass in the
session ID to session_name() or session_start() or something like that. I
forget how to do this, but I did it once when I couldn't get trans-sid to
work, and it was a one-line solution. Try to find it. Maybe session_id()
takes an optional argument.
If that fails, then here's option 2:
There is sample code for storing your session data in MySQL on the
web-site in the manual.
You could easily take that code and swap out the MySQL bits to just
read/write your own session files, or go ahead and use MySQL if it's okay
security-wise, or put the data anywhere you feel appropriate for your
application.
If that's not auitable, to answer your original question :-) is Option 3:
I think the session files consist of a series of variable names and
serialized values separated by semi-colons or something like that.
So to read/write the session files would be something not unlike:
$data = file($session_file);
$elements = explode(';', $data);
while (list(, $element) = each($elements)){
list($var, $serialized) = explode(':', $element);
$$var = unserialize($serialized);
}

RE: [PHP] Re: mediator between PHP and Perl (with sessions)
Eli, Sessions work just fine with CLI (Command Line Interpreter), although there is little need for them as a CLI script, since once started the script does not wait on user clicks of a browser for it's next set of input, therefore no need to use sessions for passing information. Most CLI scripts are started via a cron process, and if started from a webpage, the items passed to the script can be passed via command line parameters, or if passed as session variables, the session key needs to be passed to the CLI script, since CLI scripts don't have access to cookies. One advantage of using session variables when starting a CLI script, is that the session may be able to pass bigger values than can be contained in a command line. (Command line variables can be accessed in the argc/argv array like in c) and once passed this way the sessions are no longer needed since your CLI script will run to completion. If your server is a NIX box, you may have access to the character after the command name that will cause it to run as a separate shell script, but you will need to set the timeout to allow it to run long enough, and if you do not use the separate shell character, the script will be interruptible by the user who started it by clicking a button like stop on his browser. The unserialize function is indeed used for sessions, but with most newer releases of PHP register variables is turned off, which means the variables are not restored automatically (you will find them in the $_SESSION array). Sections of the manual you may want to reread are as follows; http://www.php.net/manual/en/ref.session.php http://www.php.net/manual/en/function.session-set-save-handler.php (good illustrations of what happens in sessions) http://www.php.net/manual/en/function.session-register.php (notice the notes on register variables). http://www.php.net/manual/en/function.session-id.php http://us3.php.net/manual/en/function.set-time-limit.php to allow script to run longer. http://us3.php.net/manual/en/function.shell-exec.php for starting a cli script (don't forget to start php). hope this helps, Warren Vail -Original Message- From: Eli [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 15, 2005 7:07 AM To: php-general@lists.php.net Subject: [PHP] Re: mediator between PHP and Perl (with sessions) It's quite easy to pass the session variables to the script.

Hi.. Thanks for your help. I searched a bit more, combined with your data, tested, and found a solution. :-) #!/usr/local/bin/php -q ?php //initialize parameters: if ($argc2) exit(ERROR: session id must be provide as parameter.\n); $sid=$argv[1]; //initialize session: ini_set(session.use_cookies,0); //use no session cookies session_cache_limiter(null); //use no session cache limiter session_id($sid); //set the session id as got from parameter 1 //read the session variables: echo $_SESSION[name]; ? -thanks, Eli -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
