IntlChar::charMirror

(PHP 7, PHP 8)

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

Description

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.

Liste de paramètres

codepoint: La valeur codepoint de type entier (i.e. 0x2603 pour U+2603 SNOWMAN), ou le caractère encodé en UTF-8 de type chaîne de caractères (i.e. "\u{2603}")

Valeurs de retour

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.

Le type retourné sera entier tant que le codepoint a été passé en une chaîne de type chaîne de caractères encodée en UTF-8, auquel cas, une chaîne de caractères est retournée. En cas d'échec, retourne null.

Exemples

Exemple #1 Test de différents codepoint

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

L'exemple ci-dessus va afficher :

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