    IntlChar::getPropertyValueName — Get the Unicode name for a property value

    설명

    public static string IntlChar::getPropertyValueName ( int $property , int $value [, int $nameChoice = IntlChar::LONG_PROPERTY_NAME ] )

    Returns the Unicode name for a given property value, as given in the Unicode database file PropertyValueAliases.txt.

    Note:

    Some of the names in PropertyValueAliases.txt can only be retrieved using IntlChar::PROPERTY_GENERAL_CATEGORY_MASK, not IntlChar::PROPERTY_GENERAL_CATEGORY. These include:

    • "C" / "Other"
    • "L" / "Letter"
    • "LC" / "Cased_Letter"
    • "M" / "Mark"
    • "N" / "Number"
    • "P" / "Punctuation"
    • "S" / "Symbol"
    • "Z" / "Separator"

    인수

    property

    The Unicode property to lookup (see the IntlChar::PROPERTY_* constants).

    If out of range, or this method doesn't work with the given value, FALSE is returned.

    value

    Selector for a value for the given property. If out of range, FALSE is returned.

    In general, valid values range from 0 up to some maximum. There are a couple exceptions:

    • IntlChar::PROPERTY_BLOCK values begin at the non-zero value IntlChar::BLOCK_CODE_BASIC_LATIN
    • IntlChar::PROPERTY_CANONICAL_COMBINING_CLASS values are not contiguous and range from 0..240.

    nameChoice

    Selector for which name to get. If out of range, FALSE is returned.

    All values have a long name. Most have a short name, but some do not. Unicode allows for additional names; if present these will be returned by adding 1, 2, etc. to IntlChar::LONG_PROPERTY_NAME.

    반환값

    Returns the name, or FALSE if either the property or the nameChoice is out of range.

    If a given nameChoice returns FALSE, then all larger values of nameChoice will return FALSE, with one exception: if FALSE is returned for IntlChar::SHORT_PROPERTY_NAME, then IntlChar::LONG_PROPERTY_NAME (and higher) may still return a non-FALSE value.
