IntlChar::getIntPropertyValue — Get the value for a Unicode property for a code point
$codepoint, int $property): ?intGets the property value for an enumerated or integer Unicode property for a code point. Also returns binary and mask property values.
codepointThe int codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}")
propertyThe Unicode property to lookup (see the IntlChar::PROPERTY_* constants).
Returns the numeric value that is directly the property value or, for enumerated properties, corresponds to the
numeric value of the enumerated constant of the respective property value enumeration type. Returns null on failure.
Returns 0 or 1 (for false/true) for binary Unicode properties.
Returns a bit-mask for mask properties.
Returns 0 if property is out of bounds or if the Unicode version does not
have data for the property at all, or not for this code point.
示例 #1 Testing different properties
<?php
var_dump(IntlChar::getIntPropertyValue("A", IntlChar::PROPERTY_ALPHABETIC) === 1);
var_dump(IntlChar::getIntPropertyValue("[", IntlChar::PROPERTY_BIDI_MIRRORED) === 1);
var_dump(IntlChar::getIntPropertyValue("Φ", IntlChar::PROPERTY_BLOCK) === IntlChar::BLOCK_CODE_GREEK);
?>以上示例会输出：
bool(true) bool(true) bool(true)
