    Changelog

    VersionBeschreibung
    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.
    8.0.0object is nullable now.

    Beispiele

    Beispiel #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));
    ?>

    Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    string(6) "foobar" string(6) "barfoo" string(6) "foofoo"
