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

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($conditio n)
{
$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.

I think I understand how the .= operator works, but I'm not quite

I am hoping that the manual has some examples, but I can't pull it up

If you could provide some tips on how to find it (and/or point me to
some examples), it'd be greatly appreciated.

Hi,

..= is just a shothand.
$myVar = "hello";
$myVar = $myVar." Mo";
echo $myVar;

is the same as:
$myVar = "hello";
$myVar .= " Mo";
echo $myVar;

Both will echo: "hello Mo"

It is called string concatination (glueing of strings).

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).

Online version is great. Everything you need is in there.
Just get familiar with it. :-)

If you could provide some tips on how to find it (and/or point me to
some examples), it'd be greatly appreciated.

Use the search.
If you know a functionname, just type it in, and set the select on
'functions'.

If you don't know how something is named, well, that is more difficult.
Best is to browse a little through the manual.
Start here: http://nl3.php.net/manual/en/index.php

Good luck.

Thanks.
I understand the logic and use of .= concatination, I'm hoping for an
example on this application of it.

Any advise?

Instead of directly printing out all the stuff you want to appear in the
browser with a bunch of echo or print statements, you simple write it to
a variable instead. Compare these two examples:

Direct print:

print 'foo';
print 'bar';
print 'something else';

With every print statement the data is immediately returned to the
browser and shown to the user (let aside output buffering, but that's a
different topic and doesn't matter here).

Now the delayed print:

$content = 'foo';
$content .= 'bar';
$content .= 'something else';

Until now nothing was returned to the browser, all the data was just
collected in the $content variable. The first statement directly assigns
the value 'foo' to it, the two following just append new data with the
concatenation operator. To return all the data at once to the browser
just do

print $content;

The result in the browser will be the same, just the way how it was
created on the server is different. With the second way you have more
control over the output and more flexibility in your application logic.

Concatenation (this one) on PHP really means *append*? Or does it
assigns all the content of the variable plus the concatenated str?

for example:

$var = 'abc';
$var .= 'd';
//means this?
$var = 'abcd';

Concatenatio n (this one) on PHP really means *append*? Or does it
assigns all the content of the variable plus the concatenated str?

Does it make any difference? The result is the same.

The '.' concatenates two strings and returns the result, that's all.
It doesn't really matter how the engine handles this internally.

>for example:

Yes.
