come si cripta la email?


cmq, dopo tentativi, sono arrivato a questo.

Codice PHP:
<?php require('Connections/xxx.php'); ?>


<?php
mysql_select_db($database_gcv, $gcv);
$query_Recordset1 = "SELECT password FROM `user` WHERE username = '$_POST[username]'";
$Recordset1 = mysql_query($query_Recordset1, $gcv) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);

mysql_select_db($database_gcv, $gcv);
$query_Recordset2 = "SELECT email FROM `user` WHERE username = '$_POST[username]'";
$Recordset2 = mysql_query($query_Recordset2, $gcv) or die(mysql_error());
$row_Recordset2 = mysql_fetch_assoc($Recordset2);
$totalRows_Recordset2 = mysql_num_rows($Recordset2);



//varie info per email
$oggi = date("j F Y G:i");
$ip = "$_SERVER[REMOTE_ADDR]";
$soggetto = "pass";
$to ="$Recordset2"

$body = "Ecco i tuoi dati: \nPassword: $Recordset1   \nUsername: $_POST[username]";

mail("$to","$soggetto","$body");
header ("Location: [url]http://xxxx.com/successo.php[/url]");
?>
