IntlChar::charAge — Get the "age" of the code point

### Beschreibung

public static function IntlChar::charAge(int|string `$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.

### Parameter-Liste

`codepoint`

  Ein Wert vom Typ int, der einen Codepoint darstellt (z. B. `0x2603` für U+2603 SNOWMAN) oder ein als UTF-8-String kodiertes Zeichen (z. B. `"\u{2603}"`)

### Rückgabewerte

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.

### Beispiele

Beispiel #1 Testen unterschiedlicher Codepoints

`<?php
var_dump(IntlChar::charage("\u{2603}"));
var_dump(IntlChar::charage("\u{1F576}"));
?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    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)
    }
