IntlChar::getPropertyName — Get the Unicode name for a property
説明
$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().
パラメータ
-
property -
調べたい Unicode プロパティ (定数 IntlChar::PROPERTY_* を参照ください)。
IntlChar::PROPERTY_INVALID_CODEshould not be used. Also, ifpropertyis 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. to
IntlChar::LONG_PROPERTY_NAME.
返り値
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.
