PHP 8.3.4 Released!

ReflectionClass::getMethods

(PHP 5, PHP 7, PHP 8)

ReflectionClass::getMethodsObtiene 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
<?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.
