Traits In PHP

PHP only supports single inheritance, but with the use of traits, we can achieve multiple inheritance.

A trait in PHP is like a set of reusable functions that you can add to different classes. It's a way to share code between classes without using regular inheritance.

Lets take an example:-

1. Declare Trait
We can declare a trait with the trait keyword:

<?php
trait Trait1 {
    public function method1() {
        echo "Method 1 from Trait1!";
    }
}

trait Trait2 {
    public function method2() {
        echo "Method 2 from Trait2!";
    }
}
?>

Above we have declared two traits.

2. Use of Trait
To use a trait in a class, use the use keyword:

<?php
trait Trait1 {
    public function method1() {
        echo "Method 1 from Trait1!\n";
    }
}

trait Trait2 {
    public function method2() {
        echo "Method 2 from Trait2!\n";
    }
}

class MyClass {
    use Trait1, Trait2;
}

$obj = new MyClass();
$obj->method1(); // Output: Method 1 from Trait1!
$obj->method2(); // Output: Method 2 from Trait2!
?>

I hope You understand the concept of traits.
