Parameters

domain

The domain to convert, which must be UTF-8 encoded.

options

Conversion options - combination of IDNA_* constants (except IDNA_ERROR_* constants).

variant

idna_info

This parameter can be used only if INTL_IDNA_VARIANT_UTS46 was used for variant. In that case, it will be filled with an array with the keys 'result', the possibly illegal result of the transformation, 'isTransitionalDifferent', a boolean indicating whether the usage of the transitional mechanisms of UTS #46 either has or would have changed the result and 'errors', which is an int representing a bitset of the error constants IDNA_ERROR_*.
