How can developers effectively troubleshoot and debug compatibility issues between interfaces and class implementations in PHP?

To effectively troubleshoot and debug compatibility issues between interfaces and class implementations in PHP, developers should carefully review the interface definition and ensure that the class implements all required methods with the correct signatures. They should also check for any errors or warnings generated by PHP when instantiating the class or calling its methods. Using debugging tools like Xdebug or var_dump can help identify any mismatches between the interface and class implementation.

interface MyInterface {
    public function method1();
    public function method2($param);
}

class MyClass implements MyInterface {
    public function method1() {
        // implementation
    }

    public function method2($param) {
        // implementation
    }
}
