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:
