problem with mysql_fetch_array

i am trying to print some values from a table with using mysql_fetch_array in a loop but not able to get correct values. it works fine for the loop i=0, prints all desired values but when it bocomes i=1 and starts the loop again the result values gets reset and prints the same old values. for example: outout of the query is result 1 result 2 result 3 result 4 result 5 result 6 result 7 result 8 result 9 result 10 result 11 result 12 :when i=0, it runs through the loop and prints result 1 result 2 result 3 result 4 result 5 result 6 :which is perfect. :but when i=1, it prints the same values, result 1 result 2 result 3 result 4 result 5 result 6 why is that so? can anyone help me? thanks in advance. $query4 = mysql_query("SELECT result FROM TBL_result WHERE survey_no=2";

for($i=0; $i < 2; ++$i)        //surveys

{

   for($j=0; $j < 2; ++$j)        //questions
   {                   for ($k=0; $k < 3; ++$k)    //sub-quesions
       {
           $row2 = mysql_fetch_array($query4);
           //Printing all result values one by one
       }

} }
