ADaniels > That will only set the public properties, not the private ones.

However a better alternative is to implement __set_state() as described by elias.

I think it will set privates too. if they have a setter.

if not this a design problem not implementation

if i do

$user->name = “john”

if name is public its ok or if it has magic setter (__set) or hard setter (setName($val)) method

so this will set the properties no matter its visibility

Hi Arnold,

thanks for sharing this. I was struggling with copying my class manually and that’s bullshit. Your version is nice although hacked and works like a charm

i have the reverse )

// lambda method declaration here
$methodHereIs = function() {
….
return “someReturn”;
}

$fullObjectOnTheFly = (object) array(
“aProperty” => “someValue”, #propertyOnTheFly
“aMethod” => $methodHere…. #methodOnTheFly
….more

Another way to do this would be to use a modified version of the decorator pattern:

class A
{
	protected $property = 'Set in A';
 
	public function getProperty()
	{
		return $this->property;
	}
 
	public function setProperty($property)
	{
		$this->property = $property;
	}
}
 
class B extends A
{
	public function __construct(A $class, $options = array())
	{
		$this->_class = $class;
	}
 
	public function __set($name, $value)
	{
		$this->_class->$name = $value;
	}
 
	public function __get($name)
	{
		return $this->_class->$name;
	}
 
	public function __isset($name)
	{
		return isset($this->_class->$name);
	}
 
	public function __unset($name)
	{
		unset($this->_class->$name);
	}
}
 
$a = new A();
$b = new B($a);
 
$b->setProperty('Set via B');
echo $b->getProperty();

why not this ?

function ArrayToObject($array,$class)
{
 	$obj = new $class;
 	foreach($array as $k=>$v)
 	{
 		$obj->$k = $v;
 	}
 
 	return $obj;
}

Unclean, and beautifully clever!

Recently I was attempting to cast stdClass resulted from json_decode to my own classes, that’s what I’ve came with:

hope it’ll be helpful to someone.

@leo and Simon Here's why it's usefull :

class member
{
  public static function get ($id)
  {
    return casttoclass('member', 
      db_query ("SELECT * FROM members WHERE id=$id LIMIT 1")
    );
  }

  public function getFullName ()
  {
    return $this->firstName.' '.$this->lastName;
  }
}

If you know some easiest way to do such a thing, tell me !
