$key = htmlentities($key);
}
echo "You live in ";
echo $_GET['country'];

echo " And your favorite color is "; 
switch ( $_GET['favcolor'] ) {

case "#ff0000";

You are just setting the value to a variable.

You should do something like this:

foreach( $_GET as $key => $val ) {
  $_GET[$key] = htmlentities( $val );
}

Thanks alot, it helped.
Could you explain me one more thing, my books is telling me to do it like this:

foreach ($_GET as $key => $val) {
$val = htmlentities($val);
if ( $key <> "name")

And it says " So on..." the books doesn't tell me more about this.
My question is what is this "<>" function called and what does it do?
or what should I search on google to get more info about this.

Thanks.
