I don't know PHP, but I believe these are bugs in your code:

there is no instantiation of the class--there is no "self" object.
Did you mean "static $y = $x"?

In this case, since no object was created, there is no $x to assign into
$y.

I defer this to someone who knows PHP, but if its semantics are
comparable to Java and C#, does "array(1,2)" actually create an instance
of an array? Based on the pattern of the errors above, I'd suggest you
review the concepts of object instantiation and class/instance member
variables.
