IntlChar::charAge

(PHP 7)

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

Beschreibung

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.

Parameter-Liste

codepoint

Der Integer-Wert des Codepoints (z.B. 0x2603 für U+2603 SNOWMAN) oder das Zeichen als UTF-8 String kodiert (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].

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)
}
