Declaring variable without var sign in beginning?
I have seen class that states `var _hello_kitty = array();` why they dont use $? i tried to make it `public` and `static` and it does not work without adding `$`i.e. `public static $_hello_kitty = array();`

now when i do add `$` other functions who reference it by `_hello_kitty` stop working.
