IntlChar::getPropertyValueEnum

Get the property value for a given value name

Description

public static int IntlChar::getPropertyValueEnum(int $property, string $name)

Returns the property value integer for a given value name, as specified in the Unicode database file PropertyValueAliases.txt. Short, long, and any other variants are recognized.

Note:

Some of the names in PropertyValueAliases.txt will only be recognized with 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"

Parameters

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, IntlChar::PROPERTY_INVALID_CODE is returned.

name

The value name to be matched. The name is compared using "loose matching" as described in PropertyValueAliases.txt.

Return Values

Returns the corresponding value integer, or IntlChar::PROPERTY_INVALID_CODE if the given name does not match any value of the given property, or if the property is invalid.
