IntlChar::charName

(PHP 7, PHP 8)

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

Beschreibung

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.

Parameter-Liste

codepoint

Ein Wert vom Typ int, der einen Codepoint darstellt (z. B. 0x2603 für U+2603 SNOWMAN) oder ein als UTF-8-String kodiertes Zeichen (z. B. "\u{2603}")

type

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

Rückgabewerte

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

Beispiele

Beispiel #1 Testen unterschiedlicher Codepoints

<?php
var_dump(IntlChar::charName("."));
var_dump(IntlChar::charName(".", IntlChar::UNICODE_CHAR_NAME));
var_dump(IntlChar::charName("\u{2603}"));
var_dump(IntlChar::charName("\u{0000}"));
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

string(9) "FULL STOP"
string(9) "FULL STOP"
string(7) "SNOWMAN"
string(0) ""
