What are some best practices for integrating a frontend (e.g., Angular, Vue) with a PHP backend?

When integrating a frontend framework like Angular or Vue with a PHP backend, it is important to establish a clear communication channel between the frontend and backend to exchange data. One common approach is to use RESTful APIs to handle HTTP requests and responses between the frontend and backend. This allows for seamless data transfer and interaction between the two parts of the application. 

// Example PHP code for creating a simple RESTful API endpoint
// This code snippet demonstrates how to handle a GET request and return data in JSON format

// Check if the request method is GET
if ($_SERVER['REQUEST_METHOD'] === 'GET') {
    // Retrieve data from the backend (e.g., database)
    $data = fetchData();

    // Set the response header to JSON
    header('Content-Type: application/json');

    // Return the data in JSON format
    echo json_encode($data);
}

// Function to fetch data from the backend
function fetchData() {
    // Perform database query or any other data retrieval logic
    $data = ['item1', 'item2', 'item3'];

    return $data;
}
