How to list all Object's properties and methods in PHP?

I faced this issues when trying to build a micro framework in PHP (like flask in Python ^^) for our company. So, I've recently dug into PHP core functions. It's make me happier than using framework like Yii but it took more time ^^.

Assuming that we have the following class called CodingTip:
class CodingTip{
  public $url;
  private $postNums;
  protected  $title;
  public $nullProperty;
  static $staticProperty;
  function __construct(){
   $this->url = "http://codingtip.blogspot.com";
   $this->postNums = 100;
   $this->title = "just for sharing";
  }
  
  public function method1($param = 1){
    switch ($param){
     case 1:
      return get_object_vars($this);
     case 2:
      return $this->method2();
     case 3:
      return $this->method3();
    }
    
  }
  protected function method2(){
   return get_class_methods(get_class($this));
  }
  private function method3(){
   return get_class_vars(get_class($this));
  }
}
Just create new object to test: 
//create $ct object outside class
$ct = new CodingTip();

To gets the properties of the given object. 

I used get_object_vars core function (PHP4 & PHP5)
array get_object_vars ( object $object )
Returns an associative array of defined object accessible non-static properties for the specified object in scope. If a property has not been assigned a value, it will be returned with a NULL value.
Using this function outside of class 
echo "
";
print_r(get_object_vars($ct));
echo "

";
We just got the public properties of object (url and nullProperty), and couldn't get static property, too. 
Array
(
    [url] => http://codingtip.blogspot.com
    [nullProperty] => 
)
By calling method1() without parameter of CodingTip class: 
echo "
";
print_r($ct->method1());
echo "

";
We can get all properties (excepts static one) of current object in all scopes. 
Array
(
    [url] => http://codingtip.blogspot.com
    [postNums] => 100
    [title] => just for sharing
    [nullProperty] => 
)
You can also try get_class_vars function, which will returns an associative array of declared properties visible from the current scope, with their default value. For example: 
echo "
";
print_r($ct->method1(3));
echo "

";
Result: an array of all properties which were declared in class. All attributes have null value in default.

Array
(
    [url] => 
    [postNums] => 
    [title] => 
    [nullProperty] => 
    [staticProperty] => 
)

To get all methods of the given Object 

In Php, we just use get_class_methods function to  get all methods of a class.
array get_class_methods ( mixed $class_name )
Returns an array of method names defined for the class specified by class_name. In case of an error, it returns NULL.
In order to get all methods of the given object, we need get class of that object and use get_class_methods above. For example, Let's get all methods of $ct: 
echo "
";
print_r(get_class_methods(get_class($ct)));
echo "

";
The result is array of construct and public method1 : 
Array
(
    [0] => __construct
    [1] => method1
)
In case we call method3 of CodingTip class like the followings: 
echo "
";
print_r($ct->method1(3));
echo "

";
We will get all methods of current object 
Array
(
    [0] => __construct
    [1] => method1
    [2] => method2
    [3] => method3
)
