Note that the public member $class contains the name of the class in which the method has been defined:

<?php
class 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).

<?php

class 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) {
}
}
