oci_field_is_null — Checks if the field is `NULL`

### Description

bool oci_field_is_null ( resource `$statement` , mixed `$field` )

Checks if the given `field` from the `statement` is `NULL`.

### Parameters

`statement`

  A valid OCI statement identifier.

`field`

  Can be a field's index or a field's name (uppercased).

### Notes
