ReflectionClass::getMethods

(PHP 5)

ReflectionClass::getMethodsRécupère un tableau de méthodes

Description

public array ReflectionClass::getMethods ([ int $filter ] )

Récupère un tableau de méthodes d'une classe.

Liste de paramètres

filter

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

Une combinaison des constantes ReflectionMethod::IS_STATIC, ReflectionMethod::IS_PUBLIC, ReflectionMethod::IS_PROTECTED, ReflectionMethod::IS_PRIVATE, ReflectionMethod::IS_ABSTRACT et ReflectionMethod::IS_FINAL.

Valeurs de retour

Un tableau d'objets ReflectionMethod reflétant chaque méthode.

Exemples

Exemple #1 Exemple avec 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 la méthode 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"
  }
}

The $filter uses an OR to filter the methods.

So php ReflectionMethod::IS_STATIC | ReflectionMethod::IS_PUBLIC will return all methods which are static or public methods, NOT only the methods which are both static and private.

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.

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"
  }
}
