How can the issue of empty arrays when testing the script online on a server be addressed?

When testing a script online on a server, the issue of empty arrays may arise due to differences in server configurations or environments. To address this, ensure that the necessary data is being passed to the script correctly and that the server settings are compatible with the script's requirements. Additionally, consider using error handling techniques to identify and troubleshoot any issues with empty arrays. 

// Example code snippet to handle empty arrays in PHP
$data = $_POST['data'] ?? []; // Check if data is passed via POST, otherwise initialize an empty array
if (empty($data)) {
    echo "Error: Empty array detected";
} else {
    // Process the data as needed
    foreach ($data as $item) {
        echo $item . "<br>";
    }
}
