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 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}")。

### 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].

### 例

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)
    }
