IntlChar::charMirror()

版本：php7

(PHP 7)

Get the "mirror-image" character for a code point

说明

Maps the specified character to a "mirror-image" character.

For characters with theBidi_Mirroredproperty, 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.

参数

The integer codepoint value(e.g.0x2603forU+2603 SNOWMAN), or the character encoded as a UTF-8 string(e.g."u{2603}")

返回值

Returns another Unicode code point that may serve as a mirror-image substitute, or$codepointitself if there is no such mapping or$codepointdoes not have theBidi_Mirroredproperty.

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.

范例

Testing different code points

以上例程会输出：

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