$_SESSION['temppdf']="reports/processed/temp-33689592941d9fbfcca184.pdf";
echo "<br>SESSION['temppdf']: ".$_SESSION['temppdf'];
	$temppdf = file_get_contents($_SESSION['temppdf']);
echo "<br>SESSION['temppdf']: ".$_SESSION['temppdf'];	

Expected result:

Set php.ini option "register_globals" to off.
You could also avoid this 'bug' by using some other variable name than $temppdf..

No bug here.
