    IntlChar::charMirror

    (PHP 7, PHP 8)

    IntlChar::charMirror — Get the "mirror-image" character for a code point

    Descrizione

    public static IntlChar::charMirror(int|string $codepoint): int|string|null

    Maps the specified character to a "mirror-image" character.

    For characters with the Bidi_Mirrored property, implementations sometimes need a "poor man's" mapping to another Unicode character (code point) such that the default glyph may serve as the mirror-image of the default glyph of the specified character. This is useful for text conversion to and from codepages with visual order, and for displays without glyph selection capabilities.

    Elenco dei parametri

    codepoint

    The int codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}")

    Valori restituiti

    Returns another Unicode code point that may serve as a mirror-image substitute, or codepoint itself if there is no such mapping or codepoint does not have the Bidi_Mirrored property.

    The return type is int unless the code point was passed as a UTF-8 string, in which case a string is returned. Returns null on failure.

    Esempi

    Example #1 Testing different code points

    <?php
    var_dump    (IntlChar::charMirror("A"));
    var_dump(IntlChar::charMirror("<"));
    var_dump(IntlChar::charMirror("("));
    ?>

    Il precedente esempio visualizzerà:

    string(1) "A"
string(1) ">"
string(2) ")"
