IntlChar::charAge()

版本：php7

(PHP 7)

Get the "age" of the code point

说明

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.

参数

The integer codepoint value(e.g.0x2603forU+2603 SNOWMAN), or the character encoded as a UTF-8 string(e.g."u{2603}")

返回值

The Unicode version number, as an array. For example, version1.3.31.2would be represented as[1, 3, 31, 2].

范例

Testing different code points

以上例程会输出：

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)
}
