IntlChar::charName

(PHP 7)

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

Opis

public static IntlChar::charName ( mixed $codepoint [, int $nameChoice = IntlChar::UNICODE_CHAR_NAME ] ) : string

Retrieves the name of a Unicode character.

Depending on nameChoice, 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.

Parametry

codepoint

Wartość typu integer dla punktu kodowego (np. 0x2603 dla U+2603 SNOWMAN) lub znak zakodowany jako string UTF-8 (np. "\u{2603}")

nameChoice

Which set of names to use for the lookup. Can be any of these constants:

IntlChar::UNICODE_CHAR_NAME (default)
IntlChar::UNICODE_10_CHAR_NAME
IntlChar::EXTENDED_CHAR_NAME
IntlChar::CHAR_NAME_ALIAS
IntlChar::CHAR_NAME_CHOICE_COUNT

Zwracane wartości

The corresponding name, or an empty string if there is no name for this character, or NULL if there is no such code point.
