Makes perfect since... I was isolating $city inside the loop which is why it had no value, correct?

    which is why it had no value
    But it did have a value! But only within the loop and once you left the loop the variable got out scope and did not exist anymore.

    A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
