IntlChar::charAge

(PHP 7, PHP 8)

IntlChar::charAgeGet the "age" of the code point

Descrizione

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.

Elenco dei parametri

codepoint

Valori restituiti
