IntlChar::charAge
(PHP 7)
IntlChar::charAge — Get the "age" of the code point
説明
public static IntlChar::charAge
( mixed $codepoint
) : array
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.
パラメータ
codepoint- コードポイントを表す int 型の値 (例: U+2603 SNOWMAN を表す
0x2603)、あるいは UTF-8 文字列としてエンコードされた文字 (例:"\u{2603}")。
返り値
The Unicode version number, as an array.
For example, version 1.3.31.2 would be represented as [1, 3, 31, 2].
