IntlChar::getPropertyEnum — Get the property constant value for a given property name

### 説明

public static IntlChar::getPropertyEnum ( string `$alias` ) : int

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

In addition, this function maps the synthetic names "gcm" / "General_Category_Mask" to the property `IntlChar::PROPERTY_GENERAL_CATEGORY_MASK`. These names are not in PropertyAliases.txt.

This function compliments IntlChar::getPropertyName().

### パラメータ

### 返り値

Returns an IntlChar::PROPERTY_ constant value, or `IntlChar::PROPERTY_INVALID_CODE` if the given name does not match any property.
