IntlChar::charAge — Get the "age" of the code point
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.
codepoint
コードポイントを表す integer 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}")。
The Unicode version number, as an array. For example, version 1.3.31.2 would be represented as [1, 3, 31, 2].
例1 さまざまなコードポイントの例
<?php
var_dump(IntlChar::charage("\u{2603}"));
var_dump(IntlChar::charage("\u{1F576}"));
?>
上の例の出力は以下となります。
array(4) { [0]=> int(1) [1]=> int(1) [2]=> int(0) [3]=> int(0) } array(4) { [0]=> int(7) [1]=> int(0) [2]=> int(0) [3]=> int(0) }
