Are you sure the assignment to $result is correct as $this->db->query('select...email = "' . $id . '"') (which targets DB_Sql::query()) seems to always return null.
This check looks for function or method calls that always return null and whose
return value is assigned to a variable.
Both the $myVar assignment in line 1 and the $higher assignment in line 2
are dead. The first because $myVar is never used and the second because
$higher is always overwritten for every possible time line.
The method getAll() does not seem to exist on object<Intraface_User>.
This check looks for calls to methods that do not seem to exist on a given type.
It looks for the method on the type itself as well as in inherited classes or
implemented interfaces.
This is most likely a typographical error or the method has been renamed.

This check looks for function or method calls that always return null and whose return value is assigned to a variable.
The method
getObject()can return nothing but null, so it makes no sense to assign that value to a variable.The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes.
