You need something to switch on
switch ($SOMETHING)
^^^^^^^^^^

The case expressions *must* all be different. In your example, as
isset() returns either `true` or `false` at least two of them will
be equal.

PHP will then compare the $SOMETHING to the case expressions and
continue the script execution from the case expression that matches.
If there are two or more matches, how will PHP know from which match to
start?

with if()s

if (isset($_GET['pagid'])) { echo "pagid= set"; }
elseif (isset($_GET['catid'])) { echo "catid= set"; }
elseif (isset($_GET['projectid'])) { echo "projectid= set"; }
else { echo "nothing set"; }

You might want to think about what happens if there's more than one of
those $_GET parameters set ...

Happy Coding :)
