IntlChar::charAge

(PHP 7)

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

설명

public static array IntlChar::charAge ( mixed $codepoint )

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.

인수

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

반환값

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