does something else than you think it does.
$result_deferred_comments = mssql_query($deferred_comments) or
die(mssql_error());
if it fetches any rows it will return a RESOURCE (yes, a resource which
is NEVER empty()), if it has 0 rows, it will return TRUE(yes! Again
non-empty), if it errors, it will return false (yes, empty).
Instead, use
if(false !== $result_deferred_comments true !==
$result_deferred_comments){
Minor addition; you actually want to know if the result value is a resource
or a boolean. So, why not use 'is_resource' ?
Apart from having shorter lines of code I usually prefer checking for
something that's true, but maybe that's a personal thing ;-)

From my understanding, if $result_deferred_comments is empty, than none
of
the code below the if should be executed, correct?
The actualy rows/columns that would contain the data do not appear, but
I am
still seeing the DEFERRED PAYMENT REQUEST COMMENTS table. Is the only
way
to block out EVERYTHING from being displayed if
$result_deferred_comments is
empty to use around all of the HTML and not exit out of the PHP
tags?
Or am I doing something else wrong?
Or, is it a problem with (!empty())? Since the value is an array, will
it
never be parsed as empty even if there is no data retrieved?
Below is my code:
?php
$credit_card_id = $_GET['credit_card_id'];
$deferred_comments= SELECT * FROM comments WHERE credit_card_id =
'$credit_card_id' AND request_type = 'D';
$result_deferred_comments = mssql_query($deferred_comments) or
die(mssql_error());
if(!empty($result_deferred_comments)) {
?

while ($row_deferred_comments =
mssql_fetch_array($result_deferred_comments)) {
$id_deferred_comment = $row_deferred_comments['request_id'];
$dateTime_deferred = $row_deferred_comments['comment_date'];
$deferred_comments = $row_deferred_comments['comments'];
$deferred_wrap_comments = wordwrap($deferred_comments, 60, br
/\n);
