ReflectionMethod Modifiers

ReflectionMethod::IS_STATIC int

Indicates that the method is static. Prior to PHP 7.4.0, the value was 1.

ReflectionMethod::IS_PUBLIC int

Indicates that the method is public. Prior to PHP 7.4.0, the value was 256.

ReflectionMethod::IS_PROTECTED int

Indicates that the method is protected. Prior to PHP 7.4.0, the value was 512.

ReflectionMethod::IS_PRIVATE int

Indicates that the method is private. Prior to PHP 7.4.0, the value was 1024.

ReflectionMethod::IS_ABSTRACT int

Indicates that the method is abstract. Prior to PHP 7.4.0, the value was 2.

ReflectionMethod::IS_FINAL int

Indicates that the method is final. Prior to PHP 7.4.0, the value was 4.

Hinweis:

The values of these constants may change between PHP versions. It is recommended to always use the constants and not rely on the values directly.

Changelog

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) {
}
}
