IntlChar::getPropertyName — Get the Unicode name for a property
$property
[, int $nameChoice
= IntlChar::LONG_PROPERTY_NAME
] )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 compliments 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.
nameChoice
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 nameChoice
is out of range.
If a given nameChoice
returns FALSE
, then all larger values of
nameChoice
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.
Example #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)
