The quick and dirty way is to use output buffering - [1]. The better way is to use includes/requires - [2]. This will involve moving code around the system, extracting common parts and then "include"-ing them in the right place. Also, a common practise is to only have output generated at the end of the script, rather than using a lot of echo's through out the code. A sort of manual output buffering.
