ReflectionProperty::setValue() example

<?php
class Foo {
    public static $staticProperty;
    
    public $property;
    protected $privateProperty;
}

$reflectionClass = new ReflectionClass('Foo');

$reflectionClass->getProperty('staticProperty')->setValue('foo');
var_dump(Foo::$staticProperty);

$foo = new Foo;

$reflectionClass->getProperty('property')->setValue($foo, 'bar');
var_dump($foo->property);

$reflectionProperty = $reflectionClass->getProperty('privateProperty');
$reflectionProperty->setAccessible(true);
$reflectionProperty->setValue($foo, 'foobar');
var_dump($reflectionProperty->getValue($foo));
?>

The above example will output:

string(3) "foo"
string(3) "bar"
string(6) "foobar"
