What are the differences between a trait and a class in PHP?

  • A trait cannot be instantiated on its own, while a class can.
  • A class can have properties and constants, while a trait cannot.
  • A class can implement multiple interfaces, while a trait cannot.
  • All of the above
There are several differences between traits and classes in PHP. A trait cannot be instantiated on its own; it needs to be included in a class. In contrast, a class can be instantiated to create objects. Additionally, a class can have its own properties and constants, while a trait cannot have its own properties directly. Moreover, a class can implement multiple interfaces, whereas a trait cannot directly implement interfaces. These distinctions highlight the different roles and purposes of traits and classes in PHP OOP.
