   for ($i = 1; $i <= $ncols; $i++) {
       $column_name  = oci_field_name($stmt, $i);
       $column_value = oci_result($stmt, $i);

oci_close($conn);
?>


Notes

Note:

In PHP versions before 5.0.0 you must use ocinumcols() instead. This name still can be used, it was left as alias of oci_num_fields() for downwards compatability. This, however, is deprecated and not recommended.
