IntlChar::charMirror

(PHP 7)

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

Beschreibung

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.

Parameter-Liste

codepoint

Der Integer-Wert des Codepoints (z.B. 0x2603 für U+2603 SNOWMAN) oder das Zeichen als UTF-8 String kodiert (z.B. "\u{2603}")

Rückgabewerte

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.

Der Rückgabetyp ist Integer, außer der Codepoint wurde als UTF-8 String übergeben, in welchem Fall ein String zurückgegeben wird.

Beispiele

Beispiel #1 Testen unterschiedlicher Codepoints

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

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

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