You may want to turn error reporting down to E_ALL when including the
Smarty class and then put it back to E_STRICT afterwards instead of
modifying the Smarty class directly. While Smarty is compatible with
PHP5, it is not fully compliant so using E_STRICT against it is not
appropriate, IMO.

Either is fine; just keep-in-mind PHP's evaluations for $foo=0:
empty($foo) => true
$foo == ''  => true
$foo === '' => false
