Actually, I'd like to suggest that a variable variable is the wrong tool for
this, and an array should be used instead -- something like:
$level = array(1 => array("PN", "GALUP", "VP", "PUBUP",
"STATS", "MCI", "CONLIST","CP",
"OAFS", "LO"),
2 => array("PN", "GALUP", "VP", "PUBUP",
"MCI", "CONLIST", "CP", "OAFS",
"LO")
);
if (isset($_SESSION['user']['level'])
&& isset($level[$_SESSION['user']['level']])):
foreach ($level[$_SESSION['user']['level']] as $value):
echo $value.'<br>';
endforeach;
else:
// invalid level
endif;
Cheers!
Mike
