IntlChar::isbase — Check if code point is a base character

Descrição

public static IntlChar::isbase ( mixed $codepoint ) : bool

Determines whether the specified code point is a base character. true for general categories "L" (letters), "N" (numbers), "Mc" (spacing combining marks), and "Me" (enclosing marks).

Nota:
This is different from the Unicode definition in chapter 3.5, conformance clause D13, which defines base characters to be all characters (not Cn) that do not graphically combine with preceding characters (M) and that are neither control (Cc) or format (Cf) characters.

Valor Retornado

Returns true if codepoint is a base character, false if not.
