IntlChar::getPropertyValueName()

版本：php7

(PHP 7)

Get the Unicode name for a property value

说明

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

Note:

Some of the names in PropertyValueAliases.txt can only be retrieved using IntlChar::PROPERTY_GENERAL_CATEGORY_MASK, not IntlChar::PROPERTY_GENERAL_CATEGORY. These include:

• "C"/ "Other"
• "L"/ "Letter"
• "LC"/ "Cased_Letter"
• "M"/ "Mark"
• "N"/ "Number"
• "P"/ "Punctuation"
• "S"/ "Symbol"
• "Z"/ "Separator"

参数

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

If out of range, or this method doesn't work with the given value,FALSE is returned.

Selector for a value for the given property. If out of range,FALSE is returned.

In general, valid values range from0up to some maximum. There are a couple exceptions:

• IntlChar::PROPERTY_BLOCK values begin at the non-zero value IntlChar::BLOCK_CODE_BASIC_LATIN
• IntlChar::PROPERTY_CANONICAL_COMBINING_CLASS values are not contiguous and range from 0..240.

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

All values 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$propertyor the$nameChoiceis out of range.

If a given$nameChoicereturns FALSE, then all larger values of$nameChoicewill 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.

范例

Testing different properties

以上例程会输出：

string(16) "Greek_And_Coptic"
string(5) "Greek"
string(16) "Greek_And_Coptic"
bool(false)
