ReflectionProperty::getValueGets value

Description

public ReflectionProperty::getValue(?object $object = null): mixed

Gets the property's value.

Changelog

Version Description
8.1.0 Private and protected properties can be accessed by ReflectionProperty::getValue() right away. Previously, they needed to be made accessible by calling ReflectionProperty::setAccessible(); otherwise a ReflectionException was thrown.
8.0.0 object is nullable now.

Examples

Example #1 ReflectionProperty::getValue() example

<?php
class 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');
$reflectionProperty->setAccessible(true); // only required prior to PHP 8.1.0
var_dump($reflectionProperty->getValue(new Foo));
?>

The above example will output:

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