You didn't properly close your if statement befor you started the code block.

if (empty ($e) {

Should be if (empty ($e)) {
I use a little different approach.

Try this.
if(isset($_GET['e']) and $_GET['e'] != '')
{ $e = $_GET['e']; }
else
{ $e = 'e is empty'; }
echo $e;

Here you are checking that the e var is set and that it doesn't equal nothing.

Hope this helps. There are a lot of different ways to do what you're wanting. This is just one easy way.
