In PHP, traits are a mechanism for code reuse in single inheritance languages. They allow developers to create reusable methods that can be included in multiple classes, making them particularly useful in high-traffic applications where code efficiency and organization are paramount.
Here's an example of how to create and use a trait in PHP:
// Define a trait with common methods
trait Logger {
public function log($message) {
echo "Log: " . $message . "
";
}
}
// Use the trait in a class
class User {
use Logger;
public function createUser($username) {
$this->log("User '$username' created.");
}
}
// Instantiate the User class
$user = new User();
$user->createUser("JohnDoe");
