The property
id does not exist. Did you maybe forget to declare it?
In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code: class MyClass { }
$x = new MyClass();
$x->foo = true;
Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion: class MyClass {
public $foo;
}
$x = new MyClass();
$x->foo = true;

This check looks for classes that have been defined more than once.
If you can, we would recommend to use standard object-oriented programming techniques. For example, to avoid multiple types, it might make sense to create a common interface, and then multiple, different implementations for that interface.
This also has the side-effect of providing you with better IDE auto-completion, static analysis and also better OPCode caching from PHP.
