What are the limitations of persisting data, such as $_POST[], compared to $_FILES[] in PHP?

When persisting data using $_POST[], the limitations include the inability to store files directly in the variable. This is where $_FILES[] comes in handy, as it allows for the uploading and storage of files. To overcome this limitation, you can use $_FILES[] to handle file uploads separately from other form data. 

// Example of using $_FILES[] to handle file uploads
if(isset($_FILES['file'])) {
    $file_name = $_FILES['file']['name'];
    $file_tmp = $_FILES['file']['tmp_name'];
    
    move_uploaded_file($file_tmp, "uploads/" . $file_name);
}
