Descrierea

Stil procedural

idn_to_ascii ( string $domain [, int $options = IDNA_DEFAULT [, int $variant = INTL_IDNA_VARIANT_UTS46 [, array &$idna_info ]]] ) : string

This function converts a Unicode domain name to an IDNA ASCII-compatible format.

Parametri

domain

The domain to convert, which 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_*.

Valorile întoarse

The domain name encoded in ASCII-compatible form, sau FALSE în cazul eșecului
