ReflectionClass::getMethods

(PHP 5, PHP 7, PHP 8)

ReflectionClass::getMethods — Obtiene un array de métodos

Descripción

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

Obtiene un array de métodos de una clase.

Parámetros

filter

Filtra los resultados para incluir solamente los métodos con ciertos atributos. Lo predeterminado es no filtrar nada.

Cualquier combinación de ReflectionMethod::IS_STATIC, ReflectionMethod::IS_PUBLIC, ReflectionMethod::IS_PROTECTED, ReflectionMethod::IS_PRIVATE, ReflectionMethod::IS_ABSTRACT, ReflectionMethod::IS_FINAL.

Valores devueltos

Un array de objetos ReflectionMethod que reflejan cada método.

Ejemplos

Ejemplo #1 Uso básico de ReflectionClass::getMethods()

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

$clase = new ReflectionClass('Apple');
$métodos = $clase->getMethods();
var_dump($métodos);
?>

El resultado del ejemplo sería:

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 Filtrar los resultados de ReflectionClass::getMethods()

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

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

El resultado del ejemplo sería:

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<?phpfinal 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:<?phpclass 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<?phpclass 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.
