How can the use of interfaces in PHP help achieve similar functionality to multiple inheritance without the associated drawbacks?

Using interfaces in PHP allows classes to implement multiple interfaces, providing similar functionality to multiple inheritance without the associated drawbacks such as complexity, ambiguity, and the diamond problem. By defining methods in interfaces that classes can implement, we can achieve code reuse and polymorphism without the pitfalls of traditional multiple inheritance. 

interface InterfaceA {
    public function methodA();
}

interface InterfaceB {
    public function methodB();
}

class MyClass implements InterfaceA, InterfaceB {
    public function methodA() {
        // implementation
    }

    public function methodB() {
        // implementation
    }
}
