Question: What is a trait in PHP?

Answer: A trait is similar to a class but intended to group functionality in a fine-grained and consistent way. Traits are used to declare methods in a class.

Example:

trait Loggable { 
public function log($message) 
{
 echo $message; 
} 
} 

class User { 
use Loggable; 
}
