Can ankyone help me extract the data that passes thru this form?

[virtualtom]

I have the below code in a php file and need to be able to extract the data that passes thru the file and save it to harddisk.
I would be willing to pay a fair sum if someone could help me figure this out..
[pre]
function idx_register_user(){

if(!empty($_POST['firstname']) && !empty($_POST['lastname']) && !empty($_POST['email']) && !empty($_POST['phone']) && !empty($_POST['pw'])){
$userdata = [
'user_pass' => get_option('idx_vow_mode') === 'onx' ? '8675309' : $_POST['pw'],
'user_login' => $_POST['email'],
'user_nicename' => $_POST['firstname'].'-'.$_POST['lastname'],
'user_email' => $_POST['email'],
'display_name' => $_POST['firstname'],
'first_name' => $_POST['firstname'],
'last_name' => $_POST['lastname']
];
}

[/pre]
Thank you.'

Can you clarify what you mean by "save it to harddisk"? In what manner? It looks like someone already crafted this to store the data somewhere (although that storage code is excluded from your example). I cannot imagine someone writing this just to have the data thrown away and forgotten.
