IntlChar::getPropertyEnum

(PHP 7, PHP 8)

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

说明

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 complements IntlChar::getPropertyName().

参数

alias

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

返回值

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