        echo

        echo
"<td>$column_name</td>";
        echo
"<td>$column_type</td>";
        echo
"<td>$column_size</td>";
        echo
"</tr>";
    }
       
    echo
"</table>";
   
    
oci_free_statement($stmt);  
    
oci_close($conn);   
?>

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

See also oci_num_fields() and oci_field_name().
