IntlChar::charMirror

(PHP 7)
Get the "mirror-image" character for a code point
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.

Parameters:
codepoint

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

Returns:

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 will be integer unless the code point was passed as a UTF-8 string, in which case a string will be returned.

Examples:
Testing different code points
<?php
var_dump(IntlChar::charMirror("A"));
var_dump(IntlChar::charMirror("<"));
var_dump(IntlChar::charMirror("("));
?>

The above example will output:

string(1) "E"
string(1) ">"
string(2) ")"
