(PHP 7)

Get the value for a Unicode property for a code point

说明

publicstaticIntlChar::getIntPropertyValue(mixed $codepoint,int $property): int

Gets the property value for an enumerated or integer Unicode property for a code point. Also returns binary and mask property values.

参数

$codepoint

The integer codepoint value(e.g.0x2603forU+2603 SNOWMAN), or the character encoded as a UTF-8 string(e.g."u{2603}")

$property

The Unicode property to lookup(see theIntlChar::PROPERTY_*constants).

返回值

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.

Returns0or1(for FALSE/TRUE)for binary Unicode properties.

Returns a bit-mask for mask properties.

Returns0if$propertyis out of bounds or if the Unicode version does not have data for the property at all, or not for this code point.

范例

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);
?>

以上例程会输出：

bool(true)
bool(true)
bool(true)
