Store array in cookie Options

[FMATeam]

I'm trying to store some array keys in a cookie

CODE

$USERS["user1"] = "random MD5 hash";
$USERS["user2"] = "another random MD5 hash";
$USERS["user3"] = "another random MD5 hash";

this is basically a login system and i'm trying to display the username used by any user when they login.
I'm trying to store the key in the cookie. Then recall it and print it using another file so it'll say "Welcome user1" or whatever.

Can anyone help...cheers

I don't understand your (detailed) description of what you want to do, but to answer the subject Question...

(AFAIK) a cookie holds a string. So you need to "serialise" the array info (do you really mean the keys, user1 etc, or the hashes?) then save it.

If the values are (e.g.) alphanumeric strings, xxx, yyy, and zzz, then you can save "xxx:yyy:zzz" as the cookie value, using the implode() and explode() functions.

Alternatively you may be able to use the session functions.

Anyway the answer is in the php documentation somewhere...

Your use case is *really* vague, but I'll take a shot at it. If you want to get at the keys in your $USERS array, its as simple as:

CODE

<?php
array_keys($USERS);  //This returns a scalar array with the keys of the input array as its values.
/*
So.. if your original array is:
$stuff = array("benny" => "jets", "piano" => "man");
The array that would come as the result of calling array_keys($stuff);
would look like array([0] => "benny", [1] => "piano");

*/

?>

My question is, what do you want to do with this array of keys? Do you want to store the entire array inside of a cookie? If so, you've got another step. If you want to store an individual cookie per user, your job is a lot easier...I think...again, without more details on how implement your original array, I'm not sure how to help...Going forward with the assumption that you want to store the entire array of keys in a cookie:

CODE

<?php
  $cookie_dough = serialize($stuff); // serialize returns a string that you can write in to your cookie...
// When you're ready to read your cookie and turn its contents back in to an array:
  $cookie = unserialize($string_i_read_from_cookie); //$cookie will be the array.
?>

Hope this helps!!

Cheers!
