About

In PHP, a trait is a set of member-variables and method-functions which can be added to the declaration of any class.

The autoloader treats traits like classes.

Traits are used via one sense of the use keyword.

Functions

  • trait_exists(): returns TRUE if the trait has been declared in code that has executed.

There does not appear to be a function to detect if a given class or object uses a given trait.
