Instead of echo()ing everything, store it in a string variable. Then, sum
what you need to, then echo() the sum, then echo() the string holding the
(delayed) output.

I don't think I can just store it into a variable for delayed output
because it has to be in the WHILE loop for it to itterate correctly.
If I'm wrong on this, PLEASE correct me.
I'd love to be able to do it this way (i tried something like this,
but couldn't get it to work).

You're wrong.

It should work like this:

<?php
$output='';

while($condition)
{
$output .= "Whatever";
}

echo $output;
?>

Note the use of the .= operator, check the PHP manual if you have any doubts
about how .= works.

Iván is correct. With proper programming, you can do this rather easily.

WOW!
That's great!

I think I understand how the .=3D operator works, but I'm not quite
grasping the logic.
I am hoping that the manual has some examples, but I can't pull it up
in the manual (I'm using the online version).
If you could provide some tips on how to find it (and/or point me to
some examples), it'd be greatly appreciated.
