Database array object left empty after retrieving all rows for the first time

Question

My code is like below:
(Assuming database connection is established and required database is selected)
Note: queryFire($query) is a user defined function in some file.

PHP

/* some lines of code here */
     $result = $db->queryFire("select * from ssubcategory;");
     if($result){
        while($row=mysql_fetch_array($result)){
             echo $row[0];

     /* some lines of code here */
     while($newrow=mysql_fetch_array($result))
        echo $row[0];

In the first while loop all data is retrieved and is successfully displayed in browser.
But, when it comes to last while loop, I get no data displayed in the browser with the same array variable $result.
Let me know, if the database array $result go blank after first fetch or there is some other conceptual thing I am unaware of.

In the second fetch the array is already fetched so the 'cursor' is in the end of the result set. In order to fetch the same array again, you need to go to the beginning.

Try adding

PHP

if (!mysql_data_seek($result, 0)) {
    echo "Seek failed: " . mysql_error();
}

after the first fetch.
