Problem with cookies

shamil

ok..here i just wanted to try using cookies..
but i can't get anything printed out of my next page..
here is my code...

Page where i set the cookie...
<?
setcookie("moncookie","my cookie");
?>
<a href="index.php">show my variable in next page</a>

Index.php..
echo $moncookie...

But i get nothing printed out..
Is it normal???

on the next page try using;

$HTTP_COOKIE_VARS['moncookie'];

you might have register_globals off?

THe SURE way to get it printed from anywhere in your code is to user the super globals. (at least php4 required)

echo $_COOKIE['moncookie'];

As opposed to $HTTP_COOKIE_VARS the above can be accessed directly from whithin functions without making your variable global.

It is the recommended way to do things.

$HTTP_COOKIE_VARS[]; is the depricated version of $_COOKIE[].

They are fundamentally the same, just one is old.

Actually they are fundementally different.

$COOKIES and other ($POST, $GET, $SESSION,etc) are SUPER GLOBALS unlike any other token in php. This means that this reference accesses the same data regardless of context.

$HTTP_COOKIE_VARS[] and others ($HTTP_POST_VARS, $HTTP_GET_VARS, etc) are normal array type variables that store the particular data.

What does this mean? To illustrate make a page with the following code and call it passing a variable on the query string like this

testpage.php?getvar=myvalue

////////////////////////////////////////////////////////////////
<?
function test1()
{
echo "<br>I can not see this var - " . $HTTP_GET_VARS['getvar'];
echo "<br>I can see the super global var - " . $_GET['getvar'];
//now need to reference to a global context

global $HTTP_GET_VARS;
echo "<br>AHhhh, now I can see the var - " . $HTTP_GET_VARS['getvar'];

}

test1();

?>
///////////////////////////////////////////////////////////////

You see that accessing HTTP_GET_VARS is different than the super global $_GET. Of course in root context you do not have to globolize but this just shows you that there is a fundemental difference between the super globals.
