Get the Unicode name for a property

IntlChar::getPropertyName() - IntlChar类

说明

publicstaticIntlChar::getPropertyName(int $property[,int $nameChoice=IntlChar::LONG_PROPERTY_NAME]): string

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

In addition, this function maps the propertyIntlChar::PROPERTY_GENERAL_CATEGORY_MASKto the synthetic names "gcm"/ "General_Category_Mask". These names are not in PropertyAliases.txt.

This function compliments IntlChar::getPropertyEnum().

参数

$property

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

IntlChar::PROPERTY_INVALID_CODEshould not be used. Also, if$propertyis out of range,FALSEis returned.

$nameChoice

Selector for which name to get. If out of range,FALSEis 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. toIntlChar::LONG_PROPERTY_NAME.

返回值

Returns the name, orFALSEif either the$propertyor the$nameChoiceis out of range.

If a given$nameChoicereturnsFALSE, then all larger values of$nameChoicewill returnFALSE, with one exception: ifFALSEis returned forIntlChar::SHORT_PROPERTY_NAME, thenIntlChar::LONG_PROPERTY_NAME(and higher)may still return a non-FALSEvalue.

范例

Testing different properties

以上例程会输出：

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