PHP: “Declaration of … should be compatible with that of …”

Question

I\'d like to create an interface for entities that are CRUDable (can be saved and deleted). Here is my abstract class:

abstract class AbstractCrudableEntity          


        

Answer 1

Overriding constructors is a special case:

Unlike with other methods, PHP will not generate an E_STRICT level error message when __construct() is overridden with different parameters than the parent __construct() method has.

You can not do that with other methods.

Answer 2

Your child methods must have the same number of parameters as the abstract methods in an abstract parent class.

The constructor in you example is not abstract--the child is just overriding it.
