What are the best practices for ensuring that a class implementation adheres to the type hinting requirements of an interface in PHP?

To ensure that a class implementation adheres to the type hinting requirements of an interface in PHP, you should make sure that the class implements all the methods defined in the interface with the correct parameter types and return types. This helps to enforce the contract specified by the interface and ensures that the code is more reliable and maintainable. 

interface Logger {
    public function log(string $message): void;
}

class FileLogger implements Logger {
    public function log(string $message): void {
        // implementation of log method
    }
}
