How can developers ensure that the signatures of methods in PHP are compatible to avoid errors like the one mentioned in the forum thread?

To ensure that the signatures of methods in PHP are compatible and avoid errors, developers should use type declarations for parameters and return types. This helps in specifying the types of values that can be passed to a function and returned from it, ensuring consistency and preventing unexpected errors. 

class MyClass {
    public function myMethod(int $param1, string $param2): bool {
        // Method implementation
    }
}

$object = new MyClass();
$result = $object->myMethod(10, 'example');
