idn_to_ascii

Procedural style

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

Domain to convert. In PHP 5 must be UTF-8 encoded.

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

Either INTL_IDNA_VARIANT_2003 for IDNA 2003 or INTL_IDNA_VARIANT_UTS46 for UTS #46.

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_*.

Domain name encoded in ASCII-compatible form. or FALSE on failure

Added the parameters variant and idna_info; UTS #46 support.
