IntlChar::charName

(PHP 7)

IntlChar::charName — Retrieve the name of a Unicode character

説明

public static IntlChar::charName ( mixed $codepoint [, int $nameChoice = IntlChar::UNICODE_CHAR_NAME ] ) : string

Retrieves the name of a Unicode character.

Depending on nameChoice, the resulting character name is the "modern" name or the name that was defined in Unicode version 1.0. The name contains only "invariant" characters like A-Z, 0-9, space, and '-'. Unicode 1.0 names are only retrieved if they are different from the modern names and if ICU contains the data for them.

パラメータ

codepoint

コードポイントを表す integer 型の値 (例: U+2603 SNOWMAN を表す 0x2603)、あるいは UTF-8 文字列としてエンコードされた文字 (例: "\u{2603}")。

Which set of names to use for the lookup. Can be any of these constants:

  • IntlChar::UNICODE_CHAR_NAME (default)
  • IntlChar::UNICODE_10_CHAR_NAME
  • IntlChar::EXTENDED_CHAR_NAME
  • IntlChar::CHAR_NAME_ALIAS

返り値

The corresponding name, or an empty string if there is no name for this character, or NULL if there is no such code point.
