Re: help condensing regular expressions

How about: $site_root = '/www/user/htdocs/'; <img src="<?php echo $site_root; ?>images/logo.png" /> Instead of going relative, go from the root. Or you could put $site_root as your url: $site_root = 'http://www.your_site.com/'; -- Julio Nobrega. Um dia eu chego lá: http://sourceforge.net/projects/toca Ajudei? Salvei?
