PHP how to list out all public functions of class
提问by Kristian
I've heard of get_class_methods()but is there a way in PHP to gather an array of all of the public methods from a particular class?
我听说过，get_class_methods()但在 PHP 中有没有办法从特定类中收集所有公共方法的数组？

Yes you can, take a look at the reflection classes / methods.
是的，你可以，看看反射类/方法。
http://php.net/manual/en/book.reflection.phpand http://www.php.net/manual/en/reflectionclass.getmethods.php
http://php.net/manual/en/book.reflection.php和 http://www.php.net/manual/en/reflectionclass.getmethods.php
$class = new ReflectionClass('Apple');
$methods = $class->getMethods(ReflectionMethod::IS_PUBLIC);
var_dump($methods);

As get_class_methods()is scope-sensitive, you can get all the public methods of a class just by calling the function from outside the class' scope:
由于get_class_methods()范围敏感，您可以通过从类的范围之外调用函数来获取类的所有公共方法：
So, take this class:
所以，上这门课：
class Foo {
private function bar() {
var_dump(get_class_methods($this));
}
public function baz() {}
public function __construct() {
$this->bar();
}
}
var_dump(get_class_methods('Foo'));will output the following:
var_dump(get_class_methods('Foo'));将输出以下内容：
array
0 => string 'baz' (length=3)
1 => string '__construct' (length=11)
While a call from inside the scope of the class (new Foo;) would return:
虽然来自类 ( new Foo;)范围内的调用将返回：
array
0 => string 'bar' (length=3)
1 => string 'baz' (length=3)
2 => string '__construct' (length=11)

After getting all the methods with get_class_methods($theClass)you can loop through them with something like this:
获得所有方法后，get_class_methods($theClass)您可以使用以下内容循环它们：
foreach ($methods as $method) {
$reflect = new ReflectionMethod($theClass, $method);
if ($reflect->isPublic()) {
}
}

Have you try this way?
你试过这种方法吗？
$class_methods = get_class_methods(new myclass());
foreach ($class_methods as $method_name) {
echo "$method_name\n";
}
