IntlChar::isIDPart — Check if code point is permissible in an identifier

Opis

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

Determines if the specified character is permissible in an identifier.

TRUE for characters with general categories "L" (letters), "Nl" (letter numbers), "Nd" (decimal digits), "Mc" and "Mn" (combining marks), "Pc" (connecting punctuation), and u_isIDIgnorable(c).

Informacja:
This is almost the same as Unicode's ID_Continue (IntlChar::PROPERTY_ID_CONTINUE) except that Unicode recommends to ignore Cf which is less than IntlChar::isIDIgnorable().

Parametry

Zwracane wartości

Returns TRUE if codepoint is the code point may occur in an identifier, FALSE if not.
