PHP Manual

ReflectionProperty::getValue

Gets value

Description

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

Gets the property's value.

Parameters

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.

Return Values

The current value of the property.

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"
