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

˵��

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.

����

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}")

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

����ֵ

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

����

Example #1 Testing different code points

<?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}"));
?>
