示例 #1 Testing different properties
<?php
var_dump(IntlChar::getPropertyValueEnum(IntlChar::PROPERTY_BLOCK, 'greek') === IntlChar::BLOCK_CODE_GREEK);
var_dump(IntlChar::getPropertyValueEnum(IntlChar::PROPERTY_BIDI_CLASS, 'RIGHT_TO_LEFT') === IntlChar::CHAR_DIRECTION_RIGHT_TO_LEFT);
var_dump(IntlChar::getPropertyValueEnum(IntlChar::PROPERTY_BIDI_CLASS, 'some made-up string') === IntlChar::PROPERTY_INVALID_CODE);
var_dump(IntlChar::getPropertyValueEnum(123456789, 'RIGHT_TO_LEFT') === IntlChar::PROPERTY_INVALID_CODE);
