Hi,

    yes, $text is the string passed to rtrim, which in retrun is 
supposed to overwrite what is in $text previously. Kinda like
$k = $k++;
When k was 5 before this line it will be 6 after.

That string in question is build by a loop, so I may take your advise 
and do it differently. That still doesn't explain why rtrim doesn't work 
as I expect it to.
