IntlChar::getPropertyName

(PHP 7, PHP 8)

IntlChar::getPropertyName — Get the Unicode name for a property

说明

public static IntlChar::getPropertyName(int $property, int $type = IntlChar::LONG_PROPERTY_NAME): string|false

Returns the Unicode name for a given property, as given in the Unicode database file PropertyAliases.txt.

In addition, this function maps the property IntlChar::PROPERTY_GENERAL_CATEGORY_MASK to the synthetic names "gcm" / "General_Category_Mask". These names are not in PropertyAliases.txt.

This function complements IntlChar::getPropertyEnum().

参数

property

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

IntlChar::PROPERTY_INVALID_CODE should not be used. Also, if property is out of range, false is returned.

type

Selector for which name to get. If out of range, false is returned.

All properties have a long name. Most have a short name, but some do not. Unicode allows for additional names; if present these will be returned by adding 1, 2, etc. to IntlChar::LONG_PROPERTY_NAME.

返回值

Returns the name, or false if either the property or the type is out of range.

If a given type returns false, then all larger values of type will return false, with one exception: if false is returned for IntlChar::SHORT_PROPERTY_NAME, then IntlChar::LONG_PROPERTY_NAME (and higher) may still return a non-false value.

示例

示例 #1 Testing different properties

<?php
var_dump(IntlChar::getPropertyName(IntlChar::PROPERTY_BIDI_CLASS));
var_dump(IntlChar::getPropertyName(IntlChar::PROPERTY_BIDI_CLASS, IntlChar::SHORT_PROPERTY_NAME));
var_dump(IntlChar::getPropertyName(IntlChar::PROPERTY_BIDI_CLASS, IntlChar::LONG_PROPERTY_NAME));
var_dump(IntlChar::getPropertyName(IntlChar::PROPERTY_BIDI_CLASS, IntlChar::LONG_PROPERTY_NAME + 1));
?>

以上示例会输出：

string(10) "Bidi_Class"
string(2) "bc"
string(10) "Bidi_Class"
bool(false)
