IntlChar::charMirror

(PHP 7)

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

Descrição

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.

Parâmetros

codepoint

Um codepoint integer (por exemplo 0x2603 para U+2603 SNOWMAN), ou um caracter codificado como uma string UTF-8 (exemplo "\u{2603}")

Valor Retornado

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.

O tipo retornado será integer a não ser que o codepoint seja passado como uma string UTF-8, e nesse caso uma string será retornada.

Exemplos

Exemplo #1 Testando codepoints diferentes

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

O exemplo acima irá imprimir:

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