    (PHP 7, PHP 8)

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

    Descrição

    public static IntlChar::charName(int|string $codepoint, int $type = IntlChar::UNICODE_CHAR_NAME): ?string

    Retrieves the name of a Unicode character.

    Depending on type, 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.

    Parâmetros

    codepoint

    O valor int do ponto de código (por exemplo, 0x2603 para U+2603 SNOWMAN) ou o caractere codificado como uma string UTF-8 (por exemplo, "\u{2603}").

    type

    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
    • IntlChar::CHAR_NAME_CHOICE_COUNT

    Valor Retornado

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

    Exemplos

    Exemplo #1 Testando diferentes pontos de código

    <?php
    var_dump    (IntlChar::charName("."));
    var_dump(IntlChar::charName(".", IntlChar::UNICODE_CHAR_NAME));
    var_dump(IntlChar::charName("\u{2603}"));
    var_dump(IntlChar::charName("\u{0000}"));
    ?>
