Greetings:
What is the best way to resolve paths within a document regardless of what
path it is opened under? For example: I have x.php and it contains <img
src="images..." >, (amongst other things, like php code), which resolves the
correct image path when opened under / but when x.php is read into a file
under /dir the image no longer resolves, for obvious reasons. With absolute
paths, this isn't an issue but it is with relative paths. Although I can
think of a kludge, or two, I figure that there is a more elegant solution.
Thanks in advance.

If I understand you correctly, this is really a web server issue and is
handled by the 'Alias' function in Apache (other servers may call it
something else). This function allows you to set a path prefix - say,
/images - and have all references to an image resolve to the same place.
So in your code you would have <img src="/images/foo.gif"> and it would
resolve to /my_web/images/foo.gif regardless of where it was referenced
in your web document tree.
Aliases may also be used for css, javascript or any other commonly
shared code elements.
Hope this helps.

I don't understand your problem. But, I prefer relative path and
had no issues with it.

Well to be on the safe side use absolute paths, this will definitely work.
To keep your scripts maintainable, make a configuration file where you will
put the paths in. E.g
config.php
$IMG_BASE_URL=" http://www.my-domain.com/images/";
and in your php files you write...
<img src="<?php echo $IMG_BASE_URL; ?>myImage001.jp g"/>
That way you can even change the image path later on (e.g. put all images
on a different server or load them with a script for load balancing or
whatever) and they will always work. I use this solution for my sites (well
in fact i use some method) like
function imglnk( $filename ) {
global $IMG_BASE_URL;
return $IMG_BASE_URL.$ filename;
}
and then
<img src="<?php imglnk( "myImage001.jpg " );?>/>
which isn't that kludgy and allows for arbitrary changes of the image
structure later on.

I would second this approach - in larger applications this has often been
one of the first 'include' files I've implemented, usually declaring the
path both in terms of its URL and the filesystem namespace:
// note - be consistent about trailing dir seperator
$image_url_pref ix="http://my.server.com/~colin/project/images/";
$image_file_pre fix="/home/colin/public_html/project/images/";
....
Of course, you'll then realise that the included file itself has a relative
and absolute path....but the advantage of this approach is that you can use
the path relative to one of the directories declared in the include_path
config file setting which removes the problem.

First of all, this isn't a PHP question - <img statements are html, whether
they're included in PHP or not. Now - if you were talking about include(),
require_once(), etc., you 'd be talking php.
The easiest way I've found is to just use absolute URL's for the images - i.e.
<img src="/images...">
Works everyplace on the site and you don't need to include extra files.

Don't know what problem you would have, unless you're trying to load the file
directly instead of through a webserver.
I always use a webserver for testing, though. Even have one going on my main
development system.

Is there any function for combining an absolute and a relative URL to result

I know WinInet for windows has a function that does this called

Hi there.
I have an included file (header.php) that contanis a reference to a graphic.
If I stay at the root level, then I can control the relative path of the
image.
eg. images/imagename.jpg
However, if I include this file (header.php) in a lower level directory then
of course, I end up with no image displaying as the relative path is no
longer correct.

I'm confused about paths.
I have a functionn that uses the mappath method, which I think requires a
virtual path (is that the same as a relative path?).
But this doesn't always work as the path can take the form of the following:
1. /directory/images/xyz.gif (works fine)
2. http://localhost:1234/www.mytestwebsite.com/directory/images/xyz.gif
(doesn't work)
3. http:///www.someremotesite.com/directory/images/abc.gif (doesn't work)
