Common variable for objects?

[sweahe]

Is there such a thing in PHP?
Can i declare a variable within a class that is common for all objects of that class?
So all objects of that class can read and alter this one variable?

In C++ you can write static in front of a variable to achive this, can it be done in PHP?

yes, you can use the object variable inside a function:

function what() {
$this->variablename = "value"; }

or you can initiate when you create your class:

class myobject {

var $variablename = "value";

....

function object() {

....

now you can access $this->variablename anywhere in your class.

I guess you didn't understand my question.

Say I have several instances of a class.
What I want is a variable that is the same variable for all these instances.

If object A changes the variable to a new value, when object B reads the variable it gets this new value.

Hi!

I never tried Static in the header of the class definition. I guess this can't be done.
PHP is not yet 100%-object oriented like C++, but I guess it will soon grow to these heights.

I think the only way to do it is through a global variable. Of course it detsroys the whole OOP approach. If their are a bunch of variables that need to be shared, you can make a class and require the developer to pass an oobject of this class during your objects' initialization, but this is pretty messy too.

Best,
