Remember this about variables[2]:

  1. A variable starts with the $ sign, followed by the name of the variable
  2. A variable name must start with a letter or the underscore character
  3. A variable name cannot start with a number
  4. A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
  5. Variable names are case-sensitive ($age and $AGE are two different variables)
