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

Опис

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

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).

Зауваження:
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().

Параметри

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}")

Значення, що повертаються

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