ReflectionClass::getMethods — 获取方法的数组
$filter
] )获取类的方法的一个数组。
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 的任意组合。
包含每个方法 ReflectionMethod 对象的数组。
Example #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"
}
}
Example #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"
}
}

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.

This method return an array of ReflectionMethod;
For example:
<?php
$reflection = new ReflectionClass('Test');
$aMethods = $reflection->getMethods();
var_dump($aMethods);
?>
Display:
array(2) {
[0]=> &object(ReflectionMethod)#7 (2) {
["name"]=> string(11) "__construct"
["class"]=> string(9) "Test" }
[1]=> &object(ReflectionMethod)#8 (2) {
["name"]=> string(3) "run"
["class"]=> string(9) "Test" }
}
