Both versions of the code do exactly the same: 1. Take description from memory 2. Allocate string and put the stripped version there 3. Output the string (here you might save if you don't use output buffering since no copying to the buffer happens but just output) 4. Release the memory allocated in 2.

Whoops, you're right--I was thinking it was getting returned, rather than output.
