I am building a website that hosts an online game. In this game there are lots of characters and monsters. Each of these has their own base set of numbers to determine the details of each particular character. I have one master character sheet/management pages to change/modify these characters.


  • I need to load character information once, no matter what page the user goes to or if they refresh the page. If the character doesn't change I do not want the server to recalculate everything. If the character changes stats or they change to a new character I need to recalculate the character.

Current Solution:

  • I pass the character ID, charID as a URL parameter. A function checks if it a new character or the same. It checks to see when the character was last updated. It also checks to see if there is a cookie "_created_date" and what the date is. If it does not see the cookie, or the character has been updated it builds new cookies for the character information. This function dynamically builds 40-60 cookies with all kinds of information.


  • When the function sees it should rebuild the cookies it does so, but it also logs out the user. I think this is because I am not unsetting the cookies properly. I think I am unsetting the login cookies as well.


  1. Is using cookies the right approach to managing all of this information on a client by client basis. I think it is. But it is the first time I have ever done anything on this scale.
  2. What is the best way to manage a group of cookies? In a cookie array? Should they all have the same prefix or something?
  3. How can you delete/unset this group of cookies without messing with any other cookies on the website?
  4. I see cookies being built in /tools and in /tools/edit_character. (Function checks state of cookie on about 6 different pages.) Should all these pages be under the same directory? Will deleting/unsetting cookies in a directory also remove those in child directories?
  5. Should I stick with session vars or give them expiration dates out into the future? In the case of them coming back in a couple days.

I have already seen how passing all these cookies to the client has dramatically saved server resources and time which is great. However, logging my users out all of the time is a terrible user experience that I really need to correct.

Website is on apache server, mysql, php, jQuery, js, ajax, wordpress base (the pages that do this are all custom templates).

Thank you for your suggestions and help. If there is any other information I can provide please let me know.

Here is just a piece of the cookie building function.

function fyxt_setActiveCharCookie ($charID, $fyxtAccountID) {
    global $wpdb;
    $charLvl = curBaseCharLvl($charID);
    setcookie("charLvl", $charLvl); //sets session var

    //Begin to build character information /////////////////////////////////////////////////////////////////////
    $isNPC = isNPC($charID);
    setcookie("isNPC", $isNPC); //sets session var
    if ($isNPC == 1) {
        $hordeSize = hordeSize($charID);
        setcookie("hordeSize", $hordeSize); //sets session var
        $charL1Info = getNPCInfo($charID);
        foreach ($charL1Info as $n=>$v) {
                setcookie($n, $v); //loop to set vars for all char info

Unset Function

function fyxt_unsetActiveCharCookie () {
    foreach ($_COOKIES as $c_id => $c_value)
        if ((strpos($c_id,'wordpress') !== false) || (strpos($c_id,'wp') !== false) || (strpos($c_id,'phpbb3') !== false) || (strpos($c_id,'__ut') !== false) || (strpos($c_id,'PHPSESSID') !== false)) {
            //don't delete
        } else { 
            setcookie($c_id, NULL, 1, "/fyxt-rpg-tools/", "");

    After looking at this and trying a few things I have decided to add an intermediary table to the database. In this table I will store the calculated character stats. Then I can retrieve these easily with a single select.

    Also this intermediary table will help to tackle an issue I was having with keeping multiple characters "in memory" for more advanced calculations and comparisons. This way all that is stored in a table that can be referenced instead of storing a bunch of variables either on the server or the user’s computer.

    This also seems to have a good impact on server load. I retrieve the character info and rewrite this one row in the table after a level up or other character change. If no change, I can just hold the array that is originally retrieved from this intermediary table.
