Hmmm... I was about to reply with a simple solution, but there's a problem with it
that I can't explain. Assuming the text is in $str...
I can't get preg_replace to match a newline at the end of a pattern. If I use...
$str = preg_replace('/\n=.+--\n/sU', '', $str);
...it matches nothing, but if I put a tag character at the end of the dashes, e.g.
--------------------------------x
...then use...
$str = preg_replace('/\n=.+--x/sU', '', $str);
...it works perfectly. I'm not sure why the pattern doesn't care about the first
newline, but it chokes on the second one. Any thoughts?
Thanks,
Alex
