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

说锟斤拷

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

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.

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}")

锟斤拷锟斤拷值

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.
