IntlChar::getPropertyName — Get the Unicode name for a property
$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().
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.
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 #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));
?>
以上例程会输出：
string(10) "Bidi_Class" string(2) "bc" string(10) "Bidi_Class" bool(false)
