Beispiel #1 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));
?>

You can use ReflectionProperty::setValue to set the value on static properties as well as regular instance properties.  Simply pass null in place of the instance:

<?php
class Foo {
    protected static
$bar = null;
    public static function
sayBar() {
        echo
self::$bar;
    }
}

$r = new ReflectionProperty('Foo', 'bar');
$r->setAccessible(true);
$r->setValue(null, 'foo');

Foo::sayBar(); // "foo"
?>
