IntlChar::charAge
(PHP 7, PHP 8)
IntlChar::charAge — Get the "age" of the code point
说明
Gets the "age" of the code point.
The "age" is the Unicode version when the code point was first designated (as a non-character or for Private Use) or assigned a character. This can be useful to avoid emitting code points to receiving processes that do not accept newer characters.
参数
返回值
The Unicode version number, as an array.
For example, version 1.3.31.2 would be represented as [1, 3, 31, 2].
Returns null on failure.
示例
