It is possible to get keys from $_GET in php?
<p>I just ask if it is possible to get keys from $_GET ...</p>

<p>I want to do a switch statement like</p>

<pre><code>switch($_GET key)  //here I don't know
{
   case "login": .... break;   //if "login" key exists in $_GET then show page.
   ....
}
</code></pre>

<p>Sorry for idiot question</p>
