I got this working as follows:
Code:
RewriteEngine on
RewriteRule plurk/(.*) plurk.php?user=$1
I also tested Mikor's regex, and it does match across multiple lines.
If you want to throw a number of characters limit in, you can use this:
Code:
$data = file_get_contents('http://www.plurk.com/user/Toddish');
preg_match("/\<p id\=\"about_me\"\>(.*?)<\/p\>/s",$data,$match);
print_r($match);
