IntlChar::charMirror

(PHP 7)

IntlChar::charMirrorGet the "mirror-image" character for a code point

Descrierea

public static mixed IntlChar::charMirror ( mixed $codepoint )

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.

Parametri

codepoint

Valoarea codepoint de tip integer (de ex. 0x2603 pentru U+2603 SNOWMAN) sau caracterul codificat ca string în UTF-8 (de ex. "\u{2603}")

Valorile întoarse

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.

Tipul întors va fi integer, doar dacă code point nu a fost transmis ca string UTF-8, în care caz va fi întors un string.

Exemple
