Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

Thread: Sessions in PHP

  1. #1

    Sessions in PHP

    I always understood that the session ID is stored in a cookie, but if cookies aren't supported by the user's browser for whatever reason, then PHP would be able to automatically fall back to using the query string.

    Looking through some of the documentation today, I can't work out if this is the case or not. Lots of people are passing SID explicitly in the links between pages, which I'd always assumed wasn't necessary.

    Tested it, the browser uses the cookie by default to remember its session. If the browser has cookies disabled, you need to pass allong the session id in the url to keep the session alive.

    Tested using the following code:
    PHP Code:
    $hitcounter $_SESSION['hitcounter'];
    $hitcounter += 1;
    $_SESSION['hitcounter'] = $hitcounter;

    "you have visited this page $hitcounter times <br/>";    
    "<a href='?".session_name()."=".session_id()."'>click here to keep the session alive if you have cookies disabled</a>";
    can be tested here http://pc.rvgate.nl/kirupa/sessiontest.php

    they also mention here (first comment) that the constant SID should be available.. but i didn't get that working for some reason... meh

    You can never underestimate the stupidity of the general public.
