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) {
}
}
The ReflectionMethod class
(PHP 5)

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'
?>

I have written a function which returns the value of a given DocComment tag.
Full example:
<?php
header('Content-Type: text/plain');
class Example
{
/**
* This is my DocComment!
*
* @DocTag: prints Hello World!
*/
public function myMethod()
{
echo 'Hello World!';
}
}
function getDocComment($str, $tag = '')
{
if (empty($tag))
{
return $str;
}
$matches = array();
preg_match("/".$tag.":(.*)(\\r\\n|\\r|\\n)/U", $str, $matches);
if (isset($matches[1]))
{
return trim($matches[1]);
}
return '';
}
$method = new ReflectionMethod('Example', 'myMethod');
// will return Hello World!
echo getDocComment($method->getDocComment(), '@DocTag');
?>
Maybe you can add this functionality to the getDocComment methods of the reflection classes.
