ReflectionProperty::getValue

(PHP 5, PHP 7)

ReflectionProperty::getValue — Gets value

说明

public ReflectionProperty::getValue ([ object $object ] ) : mixed

Gets the property's value.

参数

object

If the property is non-static an object must be provided to fetch the property from. If you want to fetch the default property without providing an object use ReflectionClass::getDefaultProperties() instead.

返回值

The current value of the property.

错误／异常

Throws a ReflectionException if the property is inaccessible. You can make a protected or private property accessible using ReflectionProperty::setAccessible().

范例

Example #1 ReflectionProperty::getValue() example

<?phpclass Foo {    public static $staticProperty = 'foobar';        public $property = 'barfoo';    protected $privateProperty = 'foofoo';}$reflectionClass = new ReflectionClass('Foo');var_dump($reflectionClass->getProperty('staticProperty')->getValue());var_dump($reflectionClass->getProperty('property')->getValue(new Foo));$reflectionProperty = $reflectionClass->getProperty('privateProperty');$reflectionProperty->setAccessible(true);var_dump($reflectionProperty->getValue(new Foo));?>

以上例程会输出：

string(6) "foobar"
string(6) "barfoo"
string(6) "foofoo"
