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
)
)
PHP - Manual: ReflectionClass::getMethods

ReflectionClass::getMethods
(PHP 5, PHP 7, PHP 8)
ReflectionClass::getMethods — 获取方法的数组
说明
public ReflectionClass::getMethods(int
$filter = ?): array获取类的方法的一个数组。
参数
-
filter -
过滤结果为仅包含某些属性的方法。默认不过滤。
ReflectionMethod::IS_STATIC、ReflectionMethod::IS_PUBLIC、ReflectionMethod::IS_PROTECTED、ReflectionMethod::IS_PRIVATE、ReflectionMethod::IS_ABSTRACT、ReflectionMethod::IS_FINAL的按位或（OR），就会返回任意满足条件的属性。注意: 请注意：其他位操作，例如
~无法按预期运行。这个例子也就是说，无法获取所有的非静态方法。
返回值
包含每个方法 ReflectionMethod 对象的数组。
范例
示例 #1 ReflectionClass::getMethods() 的基本用法
<?php
class Apple {
public function firstMethod() { }
final protected function secondMethod() { }
private static function thirdMethod() { }
}
$class = new ReflectionClass('Apple');
$methods = $class->getMethods();
var_dump($methods);
?>
以上例程会输出：
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"
}
}
示例 #2 从 ReflectionClass::getMethods() 中过滤结果
<?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);
?>
以上例程会输出：
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"
}
}

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.
