idn_to_utf8 - Convert domain name from IDNA ASCII to Unicode.

       Procedural style

SYNOPSIS

       string idn_to_utf8 (string  $domain, [int  $options], [int  $variant = INTL_IDNA_VARIANT_2003], [array  &$idna_info])

DESCRIPTION

	This function converts Unicode domain name from IDNA ASCII-compatible format to plain Unicode, encoded in UTF-8.

PARAMETERS

	      o $domain
		- Domain to convert in IDNA ASCII-compatible format.

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

	      o $variant
		- Either INTL_IDNA_VARIANT_2003 for IDNA 2003 or INTL_IDNA_VARIANT_UTS46 for UTS #46.

	      o $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 rep-
		resenting a bitset of the error constants IDNA_ERROR_*.

RETURN VALUES

	Domain name in Unicode, encoded in UTF-8. or FALSE on failure
