ReflectionClass::getMethods

(PHP 5, PHP 7, PHP 8)

ReflectionClass::getMethods — Récupère un tableau des méthodes

Description

public ReflectionClass::getMethods(?int $filter = null): array

Récupère un tableau des méthodes d'une classe.

Liste de paramètres

filter

Filtre les résultats pour inclure uniquement les méthodes avec certains attributs. Par défaut, aucun filtrage.

Toute disjonction au niveau du bit de ReflectionMethod::IS_STATIC, ReflectionMethod::IS_PUBLIC, ReflectionMethod::IS_PROTECTED, ReflectionMethod::IS_PRIVATE, ReflectionMethod::IS_ABSTRACT et ReflectionMethod::IS_FINAL, de sorte que toutes les méthodes avec n'importe quel des attributs fournis seront retournées.

Note: Notez que d'autres opérations au niveau du bit, par exemple ~ ne fonctionneront pas comme prévu. En d'autres termes, il n'est pas possible de récupérer toutes les méthodes non statiques, par exemple.

Valeurs de retour

Un tableau d'objets ReflectionMethod reflétant chaque méthode.

Historique

Version	Description
7.2.0	`filter` est désormais nullable.

Exemples

Exemple #1 Utilisation simple de ReflectionClass::getMethods()

<?php
class Apple {
    public function firstMethod() { }
    final protected function secondMethod() { }
    private static function thirdMethod() { }
}

$class = new ReflectionClass('Apple');
$methods = $class->getMethods();
var_dump($methods);
?>

L'exemple ci-dessus va afficher :

array(3) {
  [0]=>
  object(ReflectionMethod)#2 (2) {
    ["name"]=>
    string(11) "firstMethod"
    ["class"]=>
    string(5) "Apple"
  }
  [1]=>
  object(ReflectionMethod)#3 (2) {
    ["name"]=>
    string(12) "secondMethod"
    ["class"]=>
    string(5) "Apple"
  }
  [2]=>
  object(ReflectionMethod)#4 (2) {
    ["name"]=>
    string(11) "thirdMethod"
    ["class"]=>
    string(5) "Apple"
  }
}

Exemple #2 Filtrage des résultats depuis ReflectionClass::getMethods()

<?php
class Apple {
    public function firstMethod() { }
    final protected function secondMethod() { }
    private static function thirdMethod() { }
}

$class = new ReflectionClass('Apple');
$methods = $class->getMethods(ReflectionMethod::IS_STATIC | ReflectionMethod::IS_FINAL);
var_dump($methods);
?>

L'exemple ci-dessus va afficher :

array(2) {
  [0]=>
  object(ReflectionMethod)#2 (2) {
    ["name"]=>
    string(12) "secondMethod"
    ["class"]=>
    string(5) "Apple"
  }
  [1]=>
  object(ReflectionMethod)#3 (2) {
    ["name"]=>
    string(11) "thirdMethod"
    ["class"]=>
    string(5) "Apple"
  }
}

Note, for ReflectionClass::getMethods() not all methods in a final class are final, just the ones that have explicit modifier.
If you want to use an and operator for the filter, here is a simple implementation
<?php
final class Apple {
    public function publicMethod() { }
    public final function publicFinalMethod() { }
    protected final function protectedFinalMethod() { }
    private static function privateStaticMethod() { }
}

class MyReflection extends ReflectionClass {
    public function __construct($argument) {
        parent::__construct($argument);
    }
    
    /**
     * (non-PHPdoc)
     * @see ReflectionClass::getMethods()
     */
    public function getMethods($filter = null, $useAndOperator = true) {
        if ($useAndOperator !== true) {
            return parent::getMethods($filter);
        }
        
        $methods = parent::getMethods($filter);
        $results = array();
        
        foreach ($methods as $method) {
            if (($method->getModifiers() & $filter) === $filter) {
                $results[] = $method;
            }
        }
        
        return $results;
    }
}

$class = new MyReflection('Apple');
$methods = $class->getMethods(ReflectionMethod::IS_FINAL | ReflectionMethod::IS_PUBLIC);
var_dump($methods);

$methods = $class->getMethods(ReflectionMethod::IS_FINAL | ReflectionMethod::IS_PUBLIC, false);
var_dump($methods);
?>

Result:
array(1) {
  [0]=>
  object(ReflectionMethod)#4 (2) {
    ["name"]=>
    string(17) "publicFinalMethod"
    ["class"]=>
    string(5) "Apple"
  }
}

array(3) {
  [0]=>
  &object(ReflectionMethod)#5 (2) {
    ["name"]=>
    string(12) "publicMethod"
    ["class"]=>
    string(5) "Apple"
  }
  [1]=>
  &object(ReflectionMethod)#3 (2) {
    ["name"]=>
    string(17) "publicFinalMethod"
    ["class"]=>
    string(5) "Apple"
  }
  [2]=>
  &object(ReflectionMethod)#6 (2) {
    ["name"]=>
    string(20) "protectedFinalMethod"
    ["class"]=>
    string(5) "Apple"
  }
}

ReflectionClass::getMethods() sorts the methods by class (lowest in the inheritance tree first) then by the order they are defined in the class definition:

<?php
class A {
    public function method1() {
        
    }
    
    public function method2() {
        
    }
}

class B extends A {

    public function method3() {

    }

    public function method4() {

    }
}

$class = new ReflectionClass('B');
print_r($class->getMethods());
?>

This will output:

Array
(
    [0] => ReflectionMethod Object
        (
            [name] => method3
            [class] => B
        )

    [1] => ReflectionMethod Object
        (
            [name] => method4
            [class] => B
        )

    [2] => ReflectionMethod Object
        (
            [name] => method1
            [class] => A
        )

    [3] => ReflectionMethod Object
        (
            [name] => method2
            [class] => A
        )

Method ReflectionClass::getMethods doesn't work constantly across different versions of PHP. For following code piece

<?php
class Dummy implements Iterator
{
    public function current () {}
    public function next () {}
    public function key () {}
    public function valid () {}
    public function rewind () {}
}

$reflection = new ReflectionClass('Dummy');
$aMethods = $reflection->getMethods();
echo '# of methods: ', count($aMethods), "\n";
?>

, it outputs "# of methods: 10" on PHP 5.2.14 and PHP 5.2.17, including all methods defined in the class itself and in the interface no matter if a method has been implemented or overridden; however, it returns "# of methods: 5" on PHP 5.3.5. Based on some other tests did by my colleagues, I assume it also returns "# of methods: 5" on PHP 5.2.10 and PHP 5.3.6.
