IntlChar::charAge

(PHP 7, PHP 8)

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

Description

public static 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.

Liste de paramètres

codepoint: La valeur codepoint de type entier (i.e. 0x2603 pour U+2603 SNOWMAN), ou le caractère encodé en UTF-8 de type chaîne de caractères (i.e. "\u{2603}")

Valeurs de retour

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.
