Using mail() to send multiple emails from MySQL Query - php

Question

I got this code and it's old and I know I need to convert it to PDO (still learning) but I need to get this working right now.
I am trying to send multiple emails out based on the query. So in this particular query I get two results. So I need to send out two different emails to the group. If the query had 4 results, then I would need to send 4. Right now it is only sending the first result. How can I get it to loop through and send multiple emails.
Here is the code:
<?
// connection string ......
$production = "SELECT value1 FROM parameters WHERE name = 'IS_PRODUCTION' ";
$query = "SELECT accounts.username, email_activate.email, accounts.user_id, accounts.alt_id FROM accounts INNER JOIN email_activate ON accounts.user_id = email_activate.user_id WHERE dt_welcome = '0000-00-00 00:00:00' AND dt_start <= DATE_SUB(NOW(), INTERVAL 3 DAY)";
$result = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($result)) {
$message = "Hello ".$row['username'].", <br/><br/>";
$message .= "You recently subscribed to <bblah blah blah</b> ";
$message .= '(http://), ' ;
$message .= "the official ";
$message .= "source of <br /><br /> ";
if ($production == 'Y' ) {
$subject = "How can we Assist!";
$to = "".$row['email']."";
$result2 = mysql_query("UPDATE email_activate SET dt_welcome = NOW() WHERE user_id = '".$row['user_id']."' ");
} else {
$subject = "[TEST] Offer You Assistance";
$to = 'email1#email.com' . ', ';
$to .= 'email2#email.com ' . ', ';
$to .= 'email3#email.com';
$result2 = mysql_query("UPDATE email_activate SET dt_welcome = NOW() WHERE user_id = '".$row['user_id']."' ");
}
$headers = "Content-Type: text/html; charset=utf-8\r\n";
$queryEmail = "SELECT alt_id FROM lookup_roles WHERE spec_tag = 'public_email'";
$result3 = mysql_query($queryEmail) or die(mysql_error());
while ($row12 = mysql_fetch_array($resul3t)) {
mail($to, $subject, $message, $headers, "-f ".$row12[alt_id]."");
}
}
?>
So I fixed it, the above code works just fine. I forgot to use a different $result variable ---> Changed it from $result to $result3, this way it doesn't blank out the previous result which is why I was only getting 1 email. I knew it was something simple, just couldn't see it.
