[pmwiki-users] how to put new line in a script to wiki

[Oguz Altun]

I am writing a very simple custom directive (:querypst ... :) that will 
make querying a pmwiki simple table possible. I select the rows I like, 
and join back them to a pmwiki simple table, and return back.

Like this:

function querypst($in){
...
$out .= $header_line;
...
$out .= '\n'.$a_good_line;
...
$out .= '\n'.$another_good_line;
...
return $out;
}

I am almost there, but that '\n' does not work. In the wiki page, I see 
a table with a single long row. I tried %0a instead of '\n', too, 
without success.

What should I use instead of '\n'?

thx.
