-
INTL_MAX_LOCALE_LEN
(integer)
-
Limit on locale length, set to 80 in PHP code. Locale names longer
than this limit will not be accepted.
-
IDNA_DEFAULT
(integer)
-
Prohibit processing of unassigned codepoints in the input for IDN
functions and do not check if the input conforms to domain name ASCII rules.
-
IDNA_ALLOW_UNASSIGNED
(integer)
-
Allow processing of unassigned codepoints in the input for IDN functions.
-
IDNA_USE_STD3_RULES
(integer)
-
Check if the input for IDN functions conforms to domain name ASCII rules.
-
IDNA_CHECK_BIDI
(integer)
-
Check whether the input conforms to the BiDi rules.
Ignored by the IDNA2003 implementation, which always performs this check.
-
IDNA_CHECK_CONTEXTJ
(integer)
-
Check whether the input conforms to the CONTEXTJ rules.
Ignored by the IDNA2003 implementation, as this check is new in IDNA2008.
-
IDNA_NONTRANSITIONAL_TO_ASCII
(integer)
-
Option for nontransitional processing in
idn_to_ascii(). Transitional processing is activated
by default. This option is ignored by the IDNA2003 implementation.
-
IDNA_NONTRANSITIONAL_TO_UNICODE
(integer)
-
Option for nontransitional processing in
idn_to_utf8(). Transitional processing is activated
by default. This option is ignored by the IDNA2003 implementation.
-
INTL_IDNA_VARIANT_2003
(integer)
-
Use IDNA 2003 algorithm in idn_to_utf8() and
idn_to_ascii(). This is the default.
-
INTL_IDNA_VARIANT_UTS46
(integer)
-
Use UTS #46 algorithm in idn_to_utf8() and

-
IDNA_ERROR_INVALID_ACE_LABEL (integer)
-
IDNA_ERROR_BIDI (integer)
-
IDNA_ERROR_CONTEXTJ (integer)
-
Errors reported in a bitset returned by the UTS #46 algorithm in
idn_to_utf8() and
idn_to_ascii().

idn_to_ascii('faß.de');
will return fass.de
(Due to Germans using the ß symbol as a contraction of ss)
idn_to_ascii('faß.de', IDNA_NONTRANSITIONAL_TO_ASCII);
will return xn--fa-hia.de
(This is the correct behavior too allow faß.de and fass.de to be registered as different domain names.)
idn_to_utf8('xn--fa-hia.de');
will return fass.de
idn_to_utf8('xn--fa-hia.de', IDNA_NONTRANSITIONAL_TO_UNICODE);
will return faß.de
(Again this is the correct behavior.)
to date (MARCH 2023), the version Spanish not give info about the constant `INTL_ICU_VERSION`, take a look to English version, with details about the important constant `INTL_ICU_VERSION`
