Note

Notă:

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

Beware, the field index starts with 1, not 0. It's a bit counter-intuitive.
