How can the use of var_dump() in PHP help troubleshoot issues related to file uploads?

When troubleshooting file upload issues in PHP, using var_dump() can help by providing detailed information about the uploaded file, such as its name, type, size, and temporary location. This can help identify any errors in the file upload process, such as incorrect file types or exceeding file size limits. 

<?php
if ($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    var_dump($_FILES['file']);
    // Process the uploaded file
} else {
    echo "File upload failed with error code: " . $_FILES['file']['error'];
}
?>
