classes and superglobal arrays

[jakeone]

Can someone tell me why I can't refer to the superglobal arrays within in a class? I was trying to do the following but kept getting "parse error, unexpected T_VARIABLE":

class Basket
{
// set class attributes
var $posType = $REQUEST['searchType'];
var $posID = $REQUEST['posID'];

// remainder of class code...

}

I thought the superglobal arrays would be accessible from anywhere within my script.

Thanks

I thought the superglobal arrays would be accessible from anywhere within my script.

They are indeed.

But only constants may be used to initialise member variables in objects this way.
Elements from superglobal arrays certainly are not constants.

class Basket
{ 
	var $posType;
	var $posID;

function Basket()
{
	$this->posType = $_REQUEST['searchType'];
	$this->posID = $_REQUEST['posID'];
}
}
