PHP does give warnings about undefined array positions if you don't use quotes around them like $array1[var1] will warning (if warnings are on), but $array1["var1"] won't. I have never seen (even with error reporting turned to the maximum setting) PHP throw an error about doing something like: $robot = findRobot(); or whatever without defining "var $robot;" above this, so I'm pretty sure it's ok not to define them, and other then organizationally, it doesn't really serve a purpose since you can't define datatypes (strings, int's, or any other type can go directly into the same $robot).
