@para field_instance Field instance definition array

Parameters

$entity_type: Type of entity

$entity: Optionally, the entity. You must pass either the entity or $source_field_values

$source_field_values: Array of deltas / source field values. You must pass either this or $entity.

Return value

Three possibilities could be returned by this function:
