在PHP类中使用另一个数组启动数组时出错

Question

I try to initialize an array using another array in php class. Here is the code:

 <?php class test
{
    var $nodeDomain = array
        ("gd88" =>"10.10.104.88", "gd02" =>"10.10.104.2");
    var $node = array
        ("x86-mysql" =>$nodeDomain['gd88'],
         "x86-hbase" =>$nodeDomain['gd02']);

    function show ()
    {
        print_r($node);
    }
}
?>

I got this error: Parse error: syntax error, unexpected T_VARIABLE in /root/workspace/php/array.php on line 6

But when I run the code without using class it works fine. I mean I run the following code:

var $nodeDomain = array
    ("gd88" =>"10.10.104.88", "gd02" =>"10.10.104.2");
var $node = array
    ("x86-mysql" =>$nodeDomain['gd88'],
     "x86-hbase" =>$nodeDomain['gd02']); 

I am not quite clear about the difference of php class and php script. Can anyone explain this?

Thanks.

Try put those array-initialazing to the constructor of the test class
