11,934 PointsCode Challenge: Build a Simple PHP Application Integrating with PayPal Array Keys
In relation to Steven Weddle's thread of the same name 9 months prior to this posting, I noticed 3 people all used concatenation in their echo output within PHP to solve the code challenge. Alternatively, you could close your PHP to add an opening parenthesis in HTML, reopen PHP to add your $isbn variable, and then close the PHP to add your closing parenthesis in HTML.
Are there any functional differences between one method or the other that we may need to think how it will affect our design in the future - as far as editing and updating?
Thanks
