What are the best practices for handling dependencies and relationships between properties in PHP classes, especially in the context of external APIs like Amazon AWS?

When dealing with dependencies and relationships between properties in PHP classes, especially in the context of external APIs like Amazon AWS, it is important to use dependency injection to manage these relationships effectively. This allows for better decoupling of classes and easier testing. Additionally, using interfaces and abstract classes can help define contracts for classes that interact with external APIs, making it easier to switch implementations if needed. 

<?php

interface ExternalApiInterface {
    public function fetchData();
}

class AmazonAWSApi implements ExternalApiInterface {
    public function fetchData() {
        // Implementation to fetch data from Amazon AWS
    }
}

class DataProcessor {
    private $externalApi;

    public function __construct(ExternalApiInterface $externalApi) {
        $this->externalApi = $externalApi;
    }

    public function processData() {
        $data = $this->externalApi->fetchData();
        // Process the data
    }
}

// Implementation
$amazonAWSApi = new AmazonAWSApi();
$dataProcessor = new DataProcessor($amazonAWSApi);
$dataProcessor->processData();

?>
