> 1. fortunes are preformated by default in 1.4.3a and 1.5.1cvs.

i do understand your words, but not how this is done by sm.

anyway:

> 2. use different formating for ascii art and normal quotes.

this does not work since all the "fortunes/ascii arts" are in one single
flat text file.

> 3. replace multiple spaces with &#32; or &nbsp; and set font style to

this does not work, because multiple &#32; are not shown as multiple
spaces in the browsers.

BUUUT you gave me a wonderful idea :-)

i replaced all spaces with &#160; and thought i got it, but then, the
browser didn't break the lines at the end of the screen. similar the
</pre> html-tag.

only god knows, whats in that fortune file... 8-)
and i'm not god.


with your help, i finaly get it to work:
the code now looks something like this:

$APO = shell_exec('/usr/local/bin/fortune');
$APO = htmlspecialchars($APO);
$APO = str_replace("  ", "&#160;&#160;", $APO);
$APO = str_replace(" ", "&#32;", $APO);
$APO= nl2br($APO);

printf("<p><div style=\"font-family:'Courier
New',Courier,monospace,sans-serif\">....

which means, that all multiple spaces are replaced with whitespaces
(&#160;), and normal/single spaces are replaced with normal spaces
(&#32;).

and if i read my words, i think, i could leave out the replacement " "
with &#32; ... so the code gets smaller

ok, thank you very much for your help!!

you offered my a good solution :-)
