check whether ANY variable of type $_GET exists [closed]

Question

I know that I can check whether a particular $_GET variable exists with

isset($_GET['foo'])

But how can I check whether any $_GET variable exists? I thought that it would be as simple as

isset($_GET)

But that does not work. It always evaluates as true, even if there are no parameters in the URL.

Thanks in advance for your help!

You can use count:

// if get is empty
count($_GET) > 0 // false

// if get contains some key value pairs
count($_GET) > 0 // true
