IntlChar::charName

(PHP 7, PHP 8)

IntlChar::charName — Retrieve the name of a Unicode character

Description

public static IntlChar::charName(int|string $codepoint, int $type = IntlChar::UNICODE_CHAR_NAME): ?string

Retrieves the name of a Unicode character.

Depending on type, the resulting character name is the "modern" name or the name that was defined in Unicode version 1.0. The name contains only "invariant" characters like A-Z, 0-9, space, and '-'. Unicode 1.0 names are only retrieved if they are different from the modern names and if ICU contains the data for them.
