Hi,

i think working with exception is no problem any more. I use this in my
application and it is working fine :-).

if(file_exists("include.inc")) {
try {
include_once("include.inc");
if(class_exists("Classname")) {
$OBJECT = new Classname;
} else {
throw new Exception("Cannot instanciate");
}
} catch(Exception $Exception_obj) {
echo "Class couldn`t be instanciated.";
}
}
