Grrr what a newbie mistake (about the scope I mean)! I guess I assumed that
in a class, the $this-> was redundant for a method (it is in J++ which is
where I learned my OOP). So all my variables in the main class were 'global'
to methods in the class. My second bit of confusion is that I've made
classes before where I do this:
class myclass {
var $five = 5;
...
}
And it works fine, so you can see how the subtle difference (no var keyword
basically) could lend to confusion. I still don't fully agree with the fact
that I can't initialize the array key/value like that. It seems to me
logical that it should work after I declared the array already.
class myclass {
var $myPacket = array();
$myPacket["blah"] = "asdfasdfasdf";
...
}
Thanks guys!
