array_key_exists

Hey /prog/,

I'm working on an assignment in my web developing class, and I can't for the life of me figure out how to check if a fucking session cookie has a value in it.  We're supposed to use the array_key_exists function, but all google tells me is how to check for a specific value.  I don't care about a specific value, I just need to check if the cookie has ANYFUCKINGTHING in it. 

I tried array_key_exists("", $var) but no go.  I'm missing something I think. 

Any help? <3

This doesn't help you, you know.

That's PHP, right? If you googled ⁶⁶php array_key_exists⁹⁹ and checked http://www.php.net/manual/en/function.array-key-exists.php and scrolled down to the See Also, you'd notice a promising-sounding function array_keys().

Thanks for the response.

I saw that, however we aren't to use Isset.  we need to use array_key_exists, however a session value isn't contained in an array.

Throw PHP to garbage and start using C++ with FCGI.

I would love to do that.  But it's for class :(

If it's a cookie, wouldn't you define which values interest you? So that you may have an array of keys and you know the rest.

It is a cookie, but I just need to check for any value.  The cookie is being set based on user input, so the value could be anything.

Yes... but ``value'' in this case could refer to the value associated with a [i]key{/i], so that you may look up the existence of a value in the hash table.

Just convene a key and check if it has something associated to it.

nope nope nope

use node.js. you'll thank me later when you see just how badly it thrashes SEPPLES on hello world benchmarks

But I told you to look at array_keys(), not isset(). Your reading comprehension seems to be lacking.

This is actually a common problem. The best solution is to                               Learn D                                       

if key in request:
    print "heeeey the cookie exists"
