What is the significance of the class_uses function in PHP when dealing with traits?

The class_uses function in PHP is used to get an array of all traits used by a class. This can be useful when you need to check if a certain trait is being used by a class or to dynamically apply behaviors based on the traits used. By using the class_uses function, you can easily access and manipulate traits within your PHP classes. 

class MyTrait {
    public function myTraitMethod() {
        echo "Trait method called";
    }
}

trait MyTrait1 {
    public function myTrait1Method() {
        echo "Trait 1 method called";
    }
}

trait MyTrait2 {
    public function myTrait2Method() {
        echo "Trait 2 method called";
    }
}

class MyClass {
    use MyTrait, MyTrait1, MyTrait2;

    public function checkTraits() {
        $traits = class_uses($this);
        if (in_array('MyTrait1', $traits)) {
            echo "MyTrait1 is used";
        }
    }
}

$obj = new MyClass();
$obj->checkTraits();
