Script PHP - Flat File Database Manager + invio email

Ciao a tutti,
avrei un problema e vi chiedo gentilmente una mano.

Sto utilizzando lo script gratuito Flat File Database Manager e vorrei utilizzarlo in maniera particolare, vi spiego:

Questo script permette di aggiungere dei dati in un database fatto su file di testo.
Quello che vorrei fare è inserire un invio email ogni qualvolta viene aggiornato il database.
Ho già utilizzato altre volte la funzione mail in PHP, ma in questo caso non so proprio come piazzarla.

Grazie mille a chiunque mi aiuterà in anticipo.

Vi posto il codice:

PAGINA PRINCIPALE

Codice:

---

<?php

// Database file, i.e. file with real data
$data_file = 'formazione.txt';

// Database definition file. You have to describe database format in this file.
// See flatfile.inc.php header for sample.
$structure_file = 'giocatori.def';

// Fields delimiter
$delimiter = '  |  ';

// Number of header lines to skip. This is needed if you have some heder saved in the
// database file, like comment or description
$skip_lines = 0;

// run flatfile manager
include ('flatfile.inc.php');

?>

All'interno di quest'ultimo vorrei inserire una funzione "mail" per inviare i record aggiunti/modificati/rimossi:
codice:

Codice:

---

  /* Per inviare email in formato HTML, si deve impostare l'intestazione Content-type. */
$Subject = "Prova\r\n";
$Body = "<a href=\"http://fmiosito.com/$data_file\">formazione</a>";
$intestazioni  = "MIME-Version: 1.0\r\n";
$intestazioni .= "Content-type: text/html; charset=iso-8859-1\r\n";

/* intestazioni addizionali */
$intestazioni .= "To: admin <paolo@paolo.it>\r\n";
$intestazioni .= "From: admin <paolo@paolo.it>\r\n";
$intestazioni .= "Cc: paolo@paolo.it\r\n";
$intestazioni .= "Bcc: paolo@paolo.it\r\n";

// send email
$success = mail($Subject, $Body, $intestazioni);
