Version | Description |
---|---|
8.3.0 | Calling this method with a single argument is deprecated, ReflectionClass::setStaticPropertyValue() should be used instead to modify static properties. |
8.1.0 | Private and protected properties can be accessed by ReflectionProperty::setValue() right away. Previously, they needed to be made accessible by calling ReflectionProperty::setAccessible(); otherwise a ReflectionException was thrown. |
Example #1 ReflectionProperty::setValue() example
<?phpclass Foo { public static $staticProperty; public $property; protected $privateProperty;}$reflectionClass = new ReflectionClass('Foo');// As of PHP 8.3, setValue should no longer be used to set static property value, use setStaticPropertyValue() instead$reflectionClass->setStaticPropertyValue('staticProperty', 'foo');var_dump(Foo::$staticProperty);$foo = new Foo;$reflectionClass->getProperty('property')->setValue($foo, 'bar');var_dump($foo->property);$reflectionProperty = $reflectionClass->getProperty('privateProperty');$reflectionProperty->setAccessible(true); // only required prior to PHP 8.1.0$reflectionProperty->setValue($foo, 'foobar');var_dump($reflectionProperty->getValue($foo));?>
The above example will output:
string(3) "foo" string(3) "bar" string(6) "foobar"
