How can the PHP code be modified to accurately detect email attachments?

To accurately detect email attachments in PHP, you can use the `$_FILES` superglobal array to check for any uploaded files in the email. You can also use the `$_FILES` array to check the file type and size to ensure it is an attachment. Additionally, you can use the `is_uploaded_file()` function to verify if the file was uploaded via HTTP POST. 

if(isset($_FILES['attachment']) && is_uploaded_file($_FILES['attachment']['tmp_name'])){
    $attachment_name = $_FILES['attachment']['name'];
    $attachment_size = $_FILES['attachment']['size'];
    $attachment_type = $_FILES['attachment']['type'];
    
    // Process the attachment here
    // You can save it to a directory, send it as an email attachment, etc.
}
