How can a developer effectively troubleshoot sorting issues in PHP when integrating with front-end frameworks like AngularJS?

When troubleshooting sorting issues in PHP when integrating with front-end frameworks like AngularJS, developers can start by checking the data being sent from the front-end to the PHP backend. They should ensure that the data is being properly formatted and sorted before processing it in PHP. Additionally, developers can use PHP functions like `usort()` or `array_multisort()` to sort arrays based on specific criteria.

// Example PHP code snippet to sort an array of objects by a specific property
$data = json_decode($_POST['data']); // assuming data is sent as JSON from AngularJS

usort($data, function($a, $b) {
    return $a->property - $b->property; // replace 'property' with the actual property name
});

echo json_encode($data); // send the sorted data back to the front-end
