Optimize script for output

[kpowning]

I have the following email script below. I'm trying to set it up so that as each person in the database is emailed using the while command it will echo out using the $msg; field until all email addresses have been mailed in the database. Right now, it doesnt echo out or show any of the email addresses from the database being emailed until the whole script is completed then boom there is the list saying all have been email OK. WHAT AM I MISSING?? 🙁 please for the love of GOD.

if ((isset($HTTP_POST_VARS['Submit'])) && ($email =='')){
$msg ="Retrieving Email List!<br>";
$msg.="<u>SENDING EMAILS...</u><br><br>";
while ($row_1 = mysql_fetch_array($FanClub)){
$message = stripslashes($_POST['body']);
$getemail = $row_1['Email Address'];
$msg.="$getemail ---> OK sent!<br>";
mail($row_1['Email Address'],stripslashes($_POST['title']),"$message \r\n

}

Because all you're doing in the loop is assigning stuff to the $msg variable. That doesn't cause anything to be echoed; what will cause the contents of $msg to be echoed is if you echo $msg.

I understand that, but do you understand what I'm looking for? I want the $msg to show while the process is emailing each and every email address. So what am I doing wrong? Do I need to be echoing this information to make it work?

That's the way PHP works. The script is fully processed server side before being sent to your browser. If you want it to show the message for each loop, you can look into a using something like Ajax.

If you want PHP to echo output while it's working inside the loop, put echo statements inside the loop. Logical, that.

Use [man]flush[/man] if you need to push it past any buffers on your server.

Support for flush() varies considerably between browsers... I'd suggest using an AJAX approach
