(PHP 7)
IntlChar::charName — Retrieve the name of a Unicode character
Description
$codepoint
[, int $nameChoice
= IntlChar::UNICODE_CHAR_NAME
] ) : stringRetrieves 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.
Parameters

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

IntlChar::EXTENDED_CHAR_NAME
IntlChar::CHAR_NAME_ALIAS
IntlChar::CHAR_NAME_CHOICE_COUNT
Return Values
The corresponding name, or an empty string if there is no name for this character,
or NULL
if there is no such code point.
Examples

<?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}"));
?>
