What are the potential benefits of converting a file upload script into a function in PHP?

Converting a file upload script into a function in PHP can help improve code reusability, readability, and maintainability. By encapsulating the file upload functionality within a function, you can easily call it whenever needed without duplicating code. This approach also allows for easier testing and debugging of the file upload process. 

function uploadFile($fileInputName, $uploadDirectory) {
    $targetFile = $uploadDirectory . basename($_FILES[$fileInputName]["name"]);

    if (move_uploaded_file($_FILES[$fileInputName]["tmp_name"], $targetFile)) {
        echo "File uploaded successfully.";
    } else {
        echo "Error uploading file.";
    }
}

// Example usage
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    uploadFile("fileInputName", "uploads/");
}
