Traits example in PHP

traits.php

<?php
// In this example, we define a trait called Greetings which contains two methods: sayHello() and sayGoodbye(). 
// We then define a class called Person and use the Greetings trait within it using the use keyword. 
// This allows the Person class to have access to the methods defined in the Greetings trait.
// We create an instance of the Person class and call the sayHello() and sayGoodbye() methods, 
// which output "Hello!" and "Goodbye!", respectively.
trait Greetings {
    public function sayHello() {
        echo "Hello!";
    }
    
    public function sayGoodbye() {
        echo "Goodbye!";
    }
}

class Person {
    use Greetings;
}

$person = new Person();
$person->sayHello(); // Output: Hello!
$person->sayGoodbye(); // Output: Goodbye!
