Question

Yes I am very beginner in coding.

So what I am doing is first I get email address (from db) on which a user want to receive an email

Just like

$query = mysql_query("Select * FROM receivers WHERE id=$id")
    or die(mysql_error()); 

while ($grabit = mysql_fetch_array($query)) {

    $iAmReceiver = $grabit['email'];
}

So if a user have one email that will be simply stored in $iAmReceiver but what if a user have many email addresses for receiving emails?

Also next I use php mail function to send email, for one email address I can simply do

$ToEmail = "$iAmReceiver;
mail($ToEmail, $EmailSubject, $MESSAGE_BODY, $mailheader) or die ("Failure");

So sending mail at multiple email addresses directly depends how I store multiple email addresses??….. Something like array??

Answer 1

I am guessing something like this should work

while ($grabit = mysql_fetch_array($query)) {
    $receivers[] = $grabit['email'];
}

$ToEmail = implode("," , $receivers);

Also please consider moving upto mysqli_* or pdo. mysql_* are deprecated.
