php - Getting number of rows form SQL Server table -

-

i have problem getting right value after counted rows table. searched on web didn't find answer.

in database have table categories in have id, , count using column.

i have php code, works there other , better on this?

    $sql2 = "select count(id) categories";     $stmt2 = sqlsrv_query($conn, $sql2);     $res = sqlsrv_fetch_array($stmt2, sqlsrv_fetch_assoc);     foreach($res $row)     {         $rows = $row;     }      //if there categories display them otherwise don't     if ($rows > 0)     {         $sql = "select * categories";         $stmt = sqlsrv_query($conn, $sql);          while ($row = sqlsrv_fetch_array($stmt, sqlsrv_fetch_assoc)) {             echo "<a href='#' class='cat_links'>" . $row['category_name'] . "  - <font size='-1'>" . $row['category_description'] . "</font></a>";         }     }     else     {         echo "<p style='text-align: center'>no categories yet.</p>";     }

i think has better way convert $stmt2 variable sql resource actual number, or convert $res variable array number. if try echo whole array using foreach, print out number of rows. why use count rows now.

i can't use sqlsrv_num_rows function because error, or no answer.
