While loop looping through data twice - php

Question

So I have this code, and I've been fretting over it for several hours now and my friend and I can't find the solution. It display reviews based on a descending ID pulled from a database. This is an endless scroll type of script to eliminate pagination. For some reason when I hit the bottom of the page and run the script, the while loop is iterating through the data twice. So if its supposed to display reviews ID 5 - 10, it display 10, 9, 8, 7, 6, 5, 10, 9, 8, 7, 6, 5; instead of 10, 9, 8, 7, 6, 5. This is going to be a very large bit of code, But I hope you can help me with my problem.
Thanks in advance!!

Answer 1

Are you also sure there is no corruption in your database? you can try just
while ($review_row = mysql_fetch_assoc($mysqlQuery)) {
echo $review_row['review_title'] . "<br />";
}

Answer 2

Can you post the code that calls/posts to this script? As the others stated, it is quite possible this code is being called twice.
Also, if you run this query directly in the database, what is returned?
SELECT *
FROM `reviews`
WHERE `review_id` < (insert the id here)
ORDER BY `review_id` DESC
LIMIT 0, 10
