(PHP 7, PHP 8)

IntlChar::getPropertyValueEnum — Get the property value for a given value name

### 说明

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

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.

> 注意:

> 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"

### 参数

`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.

### 返回值

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.
