IntlChar::getPropertyEnum
(PHP 7)
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

. These names are not in PropertyAliases.txt.
This function compliments IntlChar::getPropertyName().

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

<?phpvar_dump(IntlChar::getPropertyEnum('Bidi_Class') === IntlChar::PROPERTY_BIDI_CLASS);var_dump(IntlChar::getPropertyEnum('script') === IntlChar::PROPERTY_SCRIPT);var_dump(IntlChar::getPropertyEnum('IDEOGRAPHIC') === IntlChar::PROPERTY_IDEOGRAPHIC);var_dump(IntlChar::getPropertyEnum('Some made-up string') === IntlChar::PROPERTY_INVALID_CODE);?>
