How can developers effectively troubleshoot and address errors related to interface implementation in PHP plugins or classes?

Issue: When implementing an interface in PHP plugins or classes, errors may occur if the required methods are not properly defined or if the interface itself is not correctly implemented. Solution: To troubleshoot and address these errors, carefully review the interface definition and ensure that all required methods are correctly implemented in the class that is supposed to adhere to the interface.

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

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