impossible cookie code?

[Anon]

Hey,

First of all this might be the wrong way about doing what I want, but this was the only way I could think of.

What I want to do is set a cookie with a name like "cookie5", or "cookie20" (it will always be "cookie" followed by a number).

Then, upon passing a number to the URL, as in myscript.php?num=30 I want to display the value I stored in "cookie30".

So, from what I've read when the page is loaded the cookies will be loaded into their respective names, i.e. $cookie5, $cookie20, $cookie30 etc.. thing is, how do I check if these exist, or use them? If I could somehow merge text together for a variable name I'd be sorted, like $cookie$num, but that won't work... so how else can I check?

Its driving me nuts so any help aprpeciated (if it can be done!).

Thanks,
Andy.

To check if a cookie exists use isset, to get the value call the name...

Lets say we set one cookie called mrcookie with the value helloworld...

if (isset($mrcookie)) {echo "mrcookie is set!"; }
else {echo "mrcookie is NOT set"; }

echo "mrcookie value is $mrcookie";

would give...

mrcookie value is helloworld.

Hope that was what you wanted

why not using a array? like $cookie[]?

This would be much easier.

Hope it helps.

Because it doesn't load them into an array.

It loads them into a variable of the name you labelled the cookie.

So in my case I labelled them "cookie20" and so on, so it reads them into $cookie20 - I have no choice in the matter.

I know how to check a cookie exists, using the format you describe above - the question is how do I access I cookie called $cookie35 if I don't know what its called run-time, only from a variable passed to it which holds the number.

I think you just want to work with variable variables. In other words:

$cookie20 = "stuff here";
$var = "cookie" . "20";
echo $$var;

This will print "stuff here" -- does that help?
