(PHP 5, PECL OCI8 >= 1.1.0)
oci_field_is_null — Checks if the field is NULL
Checks if the given field from the statement is NULL.
A valid OCI statement identifier.
Can be a field's index or a field's name (uppercased).
Returns TRUE if field is NULL, FALSE otherwise.
In PHP versions before 5.0.0 you must use ocicolumnisnull() instead. This name still can be used, it was left as alias of oci_field_is_null() for downwards compatability. This, however, is deprecated and not recommended.
