Member selection operator for class

[joshmpratt]

bogu, remember, this is a newbies area... Telling me that it is a "Member selection operator for class" doesn't do much for me...

I've tried looking up stuff on php.net and through google, but I cannot find a practical definition as to what this does... Anyone willing to give a newbie definition of what it does?
