ReflectionClass::getMethods

(PHP 5, PHP 7, PHP 8)

ReflectionClass::getMethods — Obtiene un array de métodos

Descripción

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

Obtiene un array de los métodos de una clase.

Parámetros

filter

Filtra los resultados para incluir únicamente los métodos con ciertos atributos. Por omisión, no se aplica ningún filtro.

Cualquier disyunción a nivel de bits de ReflectionMethod::IS_STATIC, ReflectionMethod::IS_PUBLIC, ReflectionMethod::IS_PROTECTED, ReflectionMethod::IS_PRIVATE, ReflectionMethod::IS_ABSTRACT y ReflectionMethod::IS_FINAL, de modo que se devuelven todos los métodos con cualquiera de los atributos proporcionados.

Nota: Tenga en cuenta que otras operaciones a nivel de bits, por ejemplo ~ no funcionarán como se espera. En otras palabras, no es posible obtener todos los métodos no estáticos, por ejemplo.

Valores devueltos

Un array de objetos ReflectionMethod que reflejan cada método.

Ejemplos

Ejemplo #1 Uso 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);
?>

El ejemplo anterior mostrará:

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"
  }
}

Ejemplo #2 Filtro de resultados desde 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);
?>

El ejemplo anterior mostrará:

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.
