variant Either INTL_IDNA_VARIANT_2003 [deprecated as of
PHP 7.2.0] for IDNA 2003 or INTL_IDNA_VARIANT_UTS46 [only available as of ICU 4.6] for UTS #46.
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_*.
Return Values
The domain name in Unicode, encoded in UTF-8, or false on failure
Changelog

|
| 7.2.0 | INTL_IDNA_VARIANT_2003 has been deprecated; use INTL_IDNA_VARIANT_UTS46 instead.
