The ReflectionMethod class

Note that the public member $class contains the name of the class in which the method has been defined:<?phpclass A {public function __construct() {}}class B extends A {}$method = new ReflectionMethod('B', '__construct');echo $method->class; // prints 'A'?>

We can make a "Automatic dependenci injector" in classes when her constructors depends other classes (with type hint).<?phpclass Dependence1 {    function foo() {        echo "foo";    }}class Dependence2 {    function foo2() {        echo "foo2";    }}final class myClass{    private $dep1;    private $dep2;    public function __construct(        Dependence1 $dependence1,         Dependence2 $dependence2    )    {        $this->dep1 = $dependence1;        $this->dep2 = $dependence2;            }    }// Automatic dependence injection (CLASSES)$constructor = new ReflectionMethod(myClass::class, '__construct');$parameters = $constructor->getParameters();$dependences = [];foreach ($parameters as $parameter) {    $dependenceClass = (string) $parameter->getType();    $dependences[] = new $dependenceClass();}$instance = new myClass(...$dependences);var_dump($instance);?>Results in: object(myClass)#6 (2) {  ["dep1":"myClass":private]=>  object(Dependence1)#4 (0) {  }  ["dep2":"myClass":private]=>  object(Dependence2)#5 (0) {  }}
