IntlChar::getPropertyName
(PHP 7, PHP 8)
IntlChar::getPropertyName — Get the Unicode name for a property
说明
$property, int $type = IntlChar::LONG_PROPERTY_NAME): string|falseReturns 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().
参数
-
property -
The Unicode property to lookup (see the
IntlChar::PROPERTY_*constants).IntlChar::PROPERTY_INVALID_CODEshould not be used. Also, ifpropertyis out of range,falseis returned. -
type -
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.
返回值
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.

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));
