How does the use of interfaces in PHP contribute to creating uniform interfaces for multiple developers working on a project?

Using interfaces in PHP allows developers to create a contract that specifies which methods a class must implement. This helps ensure that all classes that implement the interface will have the same method signatures, making it easier for multiple developers to work on the project without unexpected inconsistencies or errors.

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

class FileLogger implements LoggerInterface {
    public function log($message) {
        // Implement log method for file logging
    }
}

class DatabaseLogger implements LoggerInterface {
    public function log($message) {
        // Implement log method for database logging
    }
}
