PHP 8.1.0 Released!

IntlChar::getPropertyValueName

(PHP 7, PHP 8)

IntlChar::getPropertyValueNameGet the Unicode name for a property value

Açıklama

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

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

Bilginize:

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"

Değiştirgeler

property

Aranacak Unicode özelliği (bkz. IntlChar::PROPERTY_* sabitleri).

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.

Dönen Değerler

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.
