인수
-
domain
-
Domain to convert. In PHP 5 must be UTF-8 encoded.
-
options
-
Conversion options - combination of IDNA_* constants
(except IDNA_ERROR_* constants).
-
variant
-
Either INTL_IDNA_VARIANT_2003 for IDNA 2003 or
INTL_IDNA_VARIANT_UTS46 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_*.
