Getting static property from a class with dynamic class name in PHP

I have this:

  • one string variable which holds the class name ($classname)
  • one string variable with holds the property name ($propertyname)

I want to get that property from that class, the problem is, the property is static and I don't know how to do that.

If the property weren't static, it would have been:

$classname->$propertyname;

if the property were a method, I could have used call_user_function

call_user_func(array($classname, $propertyname));

But in my case, am I just lost. I am however hoping that it is possible. With the thousands of functions that PHP has, he'd better have something for this as well. Maybe I'm missing something?

Thanks!

Edit:

  • for those with eval() solutions: thanks, but it is out of the question
  • for those with get _class _vars() solutions: thanks, but it seems it returns "the default properties of the given class" (php.net), and yes, I would like that value to be changable (even though it does help me in some of the cases)

I think this is the simplest:

$foo = new ReflectionProperty('myClassName', 'myPropertyName'); 
print $foo->getValue();

One thing I noticed is that you can't set variables which are protected in static classes as the eval() command runs in a scope outside the class. The only thing to get around this would be to implement a static method inside the/every class which runs the eval(). This method could be protected as the call_user_func() [to call the setter method] also runs from inside the class.
