What are the key considerations for ensuring seamless integration between PHP backend logic and front-end sorting functionalities in AngularJS?

To ensure seamless integration between PHP backend logic and front-end sorting functionalities in AngularJS, it is crucial to establish a clear communication protocol between the two. This can be achieved by creating APIs in PHP that handle sorting requests from AngularJS and return the sorted data. Additionally, using standardized data formats (such as JSON) for data exchange can simplify the integration process.

// PHP code snippet to handle sorting requests from AngularJS
if(isset($_GET['sortBy'])) {
    $sortBy = $_GET['sortBy'];
    
    // Perform sorting logic based on $sortBy parameter
    
    // Return sorted data in JSON format
    echo json_encode($sortedData);
}
