IntlChar::getPropertyValueNameGet the Unicode name for a property value


public static IntlChar::getPropertyValueName(int $property, int $value, int $type = IntlChar::LONG_PROPERTY_NAME): string|false

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


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"

Valeurs de retour

Returns the name, or false if either the property or the type is out of range. Returns null on failure.

If a given type returns false, then all larger values of type 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.

(IntlChar::getPropertyValueName(IntlChar::PROPERTY_BLOCK, IntlChar::BLOCK_CODE_GREEK));
var_dump(IntlChar::getPropertyValueName(IntlChar::PROPERTY_BLOCK, IntlChar::BLOCK_CODE_GREEK, IntlChar::SHORT_PROPERTY_NAME));
var_dump(IntlChar::getPropertyValueName(IntlChar::PROPERTY_BLOCK, IntlChar::BLOCK_CODE_GREEK, IntlChar::LONG_PROPERTY_NAME));
var_dump(IntlChar::getPropertyValueName(IntlChar::PROPERTY_BLOCK, IntlChar::BLOCK_CODE_GREEK, IntlChar::LONG_PROPERTY_NAME + 1));
