# idn_to_ascii

(PHP 5 >= 5.3.0, PECL intl >= 1.0.2, PECL idn >= 0.1)

idn_to_ascii — Convert domain name to IDNA ASCII form.

### Opis

Styl proceduralny

string idn_to_ascii ( string `$domain` [, int `$options` = 0 [, int `$variant` = INTL_IDNA_VARIANT_2003 [, array `&$idna_info` ]]] )

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

### Parametry

`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_*.

### Zwracane wartości
