help getting website root directory

[jrthor2]

I am developing a new site that right now is at http://74.220.207.192/~zluthorg/. When I'm creating links to images/other pages, I can't just use "/" as the website root directory because that goes to http://74.220.207.192, instead of http://74.220.207.192/~zluthorg/. Is there a way to get http://74.220.207.192/~zluthorg/ from a php $_SERVER variable or some other means, so that when the site goes live, I don't have to replace a ton of /~zluthorg/ with just /?

I hope you can understand what I'm trying to do.

Thanks.

you could use ./ instead to reference the current dir, that way you don't have to keep adding the path name, but then you run into problems with sub directories...
dirname($_SERVER['PHP_SELF'])

should return the path to the current file(eg: /~zluthorg or whatever). but then that doesn't solve your problem completely, since sub dir's will still cause a problem.

my solution has always been to run a single include in all files carrying several usefull peices of info:

<?
define('im_path', '/~zluthorg/');
define('inc_path', '/home/www/includes/');
?>

then just use it like so:

<img src='<?=im_path;?>my_image.png' />

so then when the site goes live, the address will be www.zluthorg.com, I just need to change those values to "/" so they point to the web root?

[jrthor2]

is this correct?

[scragar]

well, includes path is what I use for my includes, and tend to point away from accessible files.

But yeah, you point im_path to '/' when you get your own domain/subdomain.

yeah, include files I'm good with, it's just links/images that I don't want to have to change all over my site.
