IntlChar::charName

Retrieve the name of a Unicode character

Beschreibung

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

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.

Parameter-Liste

codepoint

Der Integer-Wert des Codepoints (z.B. 0x2603 für U+2603 SNOWMAN) oder das Zeichen als UTF-8 String kodiert (z.B. "\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

Rückgabewerte

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

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) ""
