Sometimes we may want to inherit from more than one class. Since this is not possible in PHP so we can achieve  by traits.

What is a trait?

In PHP, a trait is a way  to inherit  multiple independent classes to a class achieve  Multiple inheritance.

Multiple Inheritance

trait One {
    function index_one(){
        echo " I am class One";

class Two {
    function index_two(){
            echo " I am class Two";

Here we have  Actually achieved Multiple Inheritance.


class Three extends Two {
    use One;
    function index_three(){
        echo " I am class Three";


$Obj = new Three();
echo $Obj->index_three()."<br/>";
echo $Obj->index_two()."<br/>";
echo $Obj->index_one();
