Tutorial de cómo implementar un Interfaz en PHP en Programación Orientado a Objetos

1

¿Qué representa una interfaz dentro de la arquitectura de un proyecto orientado a objetos en PHP?

2

Al declarar métodos dentro de una interfaz, ¿qué regla de visibilidad se debe cumplir estrictamente según el estándar de PHP mostrado en el video?

3

¿Qué ocurre si una clase utiliza la palabra clave implements para una interfaz, pero no define uno de los métodos declarados en ella?

4

¿Cuál es una de las ventajas de poder extender una interfaz de otra en PHP?

Explicación

La interfaz define la estructura que la clase debe seguir obligatoriamente

El uso de private o protected en una interfaz generará un error de sistema.

Es obligatorio que la clase implemente cada uno de los métodos declarados en la interfaz.

Aunque PHP no permite herencia múltiple entre clases, la extensión de interfaces permite crear estructuras jerárquicas similares.
