# IntlChar::charAge

(PHP 7)

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

### Description

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.

### Parameters

`codepoint`

  The int codepoint value (e.g. `0x2603` for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. `"\u{2603}"`)

### Return Values

The Unicode version number, as an array. For example, version 1.3.31.2 would be represented as `[1, 3, 31, 2]`.

### Examples

Example #1 Testing different code points

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

The above example will output:

    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)
    }
