Hi:
after a deep look, I think it's not a bug.
the exception in the catch block is only a local var of that block.
I think you should change you codes like following to accomplish
your requirement:
function foo(&$exception)
{
try {
throw new Exception('foo error');
} catch (Exception $e) {
var_dump(gettype($e));
$exception = $e;
echo $e->getMessage() . "\n";
}
}
foo($error);
var_dump(gettype($error));
thanks
