A trait in PHP is a mechanism that allows incorporating a set of methods into a class for use in other classes without the need for inheritance. Traits provide the ability to use multiple inheritance, enabling classes to contain functionality from various sources.
Example usage of a trait in PHP:
trait Logger {
public function log($message) {
echo $message;
}
}
class User {
use Logger;
public function register() {
// User registration implementation
$this->log('User registered successfully');
}
}
$user = new User();
$user->register();
In this example, the User class uses the Logger trait, which contains the log method. The User class inherits the functionality of the trait and can use its method.
