How can PHP developers troubleshoot and resolve issues with empty file types and names during uploads on different server configurations?

When encountering issues with empty file types and names during uploads on different server configurations, PHP developers can troubleshoot and resolve the problem by checking for the presence of a file before attempting to process it. This can be done by validating the file input using PHP functions like `isset()` or `empty()` to ensure that a file has been selected before proceeding with the upload process. 

if(isset($_FILES['file']['name']) && $_FILES['file']['size'] > 0) {
    // Process file upload here
} else {
    echo "Please select a file to upload.";
}
