IntlChar::charFromName — Find Unicode character by name and return its code point value

説明

public static IntlChar::charFromName ( string $characterName [, int $nameChoice = IntlChar::UNICODE_CHAR_NAME ] ) : int

Finds a Unicode character by its name and returns its code point value.

The name is matched exactly and completely. If the name does not correspond to a code point, null is returned.

A Unicode 1.0 name is matched only if it differs from the modern name. Unicode names are all uppercase. Extended names are lowercase followed by an uppercase hexadecimal number, and within angle brackets.

パラメータ

characterName

Full name of the Unicode character.

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

返り値

The Unicode value of the code point with the given name (as an int), or null if there is no such code point.
