RE: [PHP] Re: help condensing regular expressions

Hi For some reason $DOCUMENT_ROOT always points to /usr/local/apache/htocs even when the actual document root on the virtual domain is /usr/local/apache/domains/domain.com/www/ You can use PATH_TRANSLATED but that doesn't solve the http side when you may need to find the images directory from an included file :) My little relative_root does the trick nicely for both situations, just I think the expression I use is very brutal and there is probably a more elegant way to arrive at the same result.

why not use somthing like this then include($DOCUMENT_ROOT."/include/mysql_connect.inc"); Robert W.

Hi I am trying to calculate how far into a directory structure I am so that

I

can include images and include files without having to hard code them. I need to turn $PHP_SELF which could be /admin/emails/index.php into

../../

which I can then use to get to any directory from root. like IMG src=<?echo $relative_root?>images/logo.png Regular expressions leave me cold but I have come up with the following monster which works $relative_root = preg_replace("<\/[[:alnum:]]+>","../", preg_replace("</[[:alnum:]]+$>","",strtok($PHP_SELF,"."))); Anybody have a better solution? Thanks for any help. Tom
