Thanks - I never knew that the single or double quotes could make such
a serious difference... and your suggestion worked...

>> $string = str_replace(array("\n","\r"),array('\n','\r'), $string);

For anyone reading this post in the future they should take great care
to ensure they are using the correct source string - my data returns
from my DB in a multi-dimensional array and I was referencing it
incorrectly which resulted in no output. I had originally assumed the
above solution did not work but then I printed my source data before
and after the result of str_replace and discovered they were both
blank... simple mistake but possible even for the most talented of the
talented :)
