PHP takes a query string, e.g. the part after the question mark in:

http://example.net/foo.php?a=1&b=2&c=3

and splits it up using ampersands (although it can be configured to
use different characters instead/as well) like this:

a=1
b=2
c=3

and then uses these to populate a global array called $_GET, such that:

$_GET['a'] = 1;
$_GET['b'] = 2;
$_GET['c'] = 3;

This $_GET array can now be accessed by "foo.php" and used as it likes.
(foo.php is also able to access the raw, unprocessed query string, but
this is not usually very useful.)

In your example, statistics.php sees:

$_GET['fileName'] = 'displayIncidents.php';
$_GET['delete'] = 'true';

so the following code:

$file=$_GET['fileName'];
echo "Requested File is: ".$file;
include($file);

works.
