说明

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

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.

This function compliments IntlChar::getPropertyName() .

参数

返回值
