The browser is prepending the domain to the path of the css file.

It's the equivalent of:

http(s)://domain.com/includes/sites.css

The browser is looking for the file from the *WEB* root not the
filesystem root. (Forgive me if that is not the proper nomenclature.)
The browser is not doing anything special at all.

Oops, my bad. I missed the slash in front. I've never run into a
problem using this:



and I've never placed a period at the beginning.


But you raise an interesting point. Is the server telling the browser
where the doc root is, or is the browser just guessing by dumping
everything after the domain name and using what's left as the doc
root.

No... You missed the point of this whole thread which was explained in
point 1 and point 2 of the "Problem" section.
Restated in different words is how do you write some code which is
dynamic enough to withstand reorganization of folders either on the
same host, a different host (maybe with a different OS too), or a
mixture of any.
In HTML, a css declaration as follows:

er does it really?

I'm pretty sure the url is ./includes/site.css i.e. the include subdir of the
dir in which the html file that includes the link tag is in. if you move the
html file up or down a dir then the link to the css file will break
maybe browsers are smart enough to also check /includes/site.css
works regardless of where the page is, where it's moved to, and
regardless of how many folders down it is as long as there is indeed a
folder off the site root called "includes" and as long as there is a
file in that folder called "site.css".
How do we mimic that capability in PHP so pages don't have to be
re-written if point 1 or point 2 of the "Problem" are met?

I only do stuff for my own server which actually creates a couple
 of server variables called:

 SERVER["DOMAIN_ROOT"] and SERVER["PHPINCDIR"] which have the same
 values as the script we just cobbled together for each virtual
 domain.
 I don't suffer from the problem of lack of access to the
 include directory, So all my domains follow this layout:

/usr/local/apache/domains/domain1.com //root and chroot for ftp
 access
/usr/local/apache/domains/domain1.com/www web document root

/usr/local/apache/domains/domain1.com/include for all include files

If a hosting provider locks you in to the document root it's time to
change provider :)
As for naming convention I use .inc and stop apache from serving .inc
files.

I do this for security as I have things in include that I don't want
to be avaiable directly to the browser Also you don't need a path for include
files you can just do:

include('somefile.php');

and it will be found regardless of where the script is located.

Hello Tom,

H. Not quite what I'm looking for. I set up some test folders and
files on a development machine to play with your script.

Here's how it was laid out:

The document root for the test site:
"c:\sambar\docs\test"

A subfolder of the doc root
"folder1"

A subfolder of the above folder1
"folder2"

Placing a file called test.php (containing your script) in all three
places (doc root, folder1, folder1/folder2) gives you the following
respectively. 

Root: c:\sambar\docs\test\test.php
Document root: c:\sambar\docs\test\test.php
Base: test.php
Include: c:\cambar\docs\test\include
OS: winnt
Include: c:\cambar\docs\test\include;.;C:\php5\pear

Ultimately, this would be the correct folder I would want, but see the
below two tests.

Root: c:\sambar\docs\test\folder1\test.php
Document root: c:\sambar\docs\test\folder1\test.php
Base: test.php
Include: c:\sambar\docs\test\folder1\include
OS: winnt
Include: c:\sambar\docs\test\folder1\include;.;C:\php5\pear

Root: c:\sambar\docs\test\folder1\folder2\test.php
Document root: c:\sambar\docs\test\folder1\folder2\test.php
Base: test.php
Include: c:\sambar\docs\test\folder1\folder2\include
OS: winnt
Include: c:\sambar\docs\test\folder1\folder2\include;.;C:\php5\pear


I don't see where your script is giving me the include folder I want.

Thanks though.

R> http://php.net/set_include_path
Ok... Maybe I should put all this together in one e-mail so that all
the issues can be looked at...
The problem:
Finding a reliable method to include files, keeping in mind the
following:
1. The site could be moved to a completely new host which could be of
   a different OS, and/or web server software, and could either be the
   one and only site on that host (dedicated server), or could be a
   virtual host (shared server).
2. The site could remain on the same host but is required to move to a
   new path. i.e. from htdocs/mysite to htdocs/mynewsite
3. The web host may or may not allow the use of .htaccess (Some Sambar
   configurations for example).
4. The method used would not affect any other virtual hosts. Meaning,
   the method used must be independent for each virtual host.
5. The method used would not utilize a folder where other virtual
   hosts could gain access to the included file (php.ini
   include_path).
6. The method (and this is the important one IMHO) would not require
   editing "x" number of pages in a site to change some static path
   that was set on each page.
7. The method used would not require a dedicated "include" file in
   every single folder of the site that could be included because it's
   in the same folder as the page needing it, because those would all
   have to be edited to fix the path if condition 1 or 2 was met.
Previously proposed solutions:
1. PHP.ini include_path
   This affects all virtual hosts and would require administrative
   overhead to prevent the owners of each virtual host from gaining
   access to other virtual host's include files. I suppose you could
   set it to something like: include_path="/php/includes" and have a
   separate subfolder under that for each virtual host. But since that
   folder is outside the web folder, there would have to be some
   mechanism (additional FTP account) for each person to gain access
   to their own include folder to add/edit/delete files in that
   folder. Then if the site is moved and they aren't using an
   include_path, you have to fix all your pages.
2. set_include_path
   This means if your site moves, you must edit "x" number of pages in
   the site to correct the path.
3. An include file in every directory to set the include path.
   You'd have to edit "x" number of these files to correct the path if
   the site moves. This would be much less work than the previous
   item, but it could be a lot of work on very big sites where you
   don't have shell accounts to do some scripted find/replace with.
4. Use the full URL to the file in the include statement.
   See item 2.
5. $_SERVER["DOCUMENT_ROOT"] and $_SERVER['PATH_TRANSLATED']
   Not always available or incorrect see
   mid:[EMAIL PROTECTED]
I may have missed some things, and if I've misunderstood how something
should work, then please let me know. I'm just looking for a more or
less foolproof method which doesn't require fixing code if the site is
moved. The closest I can come to it is the function I wrote but is a
pain because you have to put it in every page where you need an
included file. Granted, you only have to do it once, and then you're
done and a site move wont affect it, but it's still kludgy if you ask
me.
***

function dynRoot() 
{ 
  $levels = substr_count($_SERVER['PHP_SELF'],"/"); 

  for ($i=0; $i < $levels - 1; $i++) 
  { 
$relativeDir .= "../"; 
  } 

  return $relativeDir; 
}
?>
***

and then calling it as such:
include(dynRoot() . 'includes/db_connect.php');
I've had to move client sites between Sambar, Apache, IIS and Windows,
Linux. Most times I've had to go in and fix include paths because one
of the above solutions were originally used and wasn't viable on the
new host.
Thanks.

Never seen it.

Only your post w/ a reference to a thread I didn't go re-read made me
think it could happen...

I don't really spend a lot of time porting code from server to server,
though.

Your solution seems to be pretty bulletproof. I definitely appreciate
it. Just wondering though for posterity sake, have you or anyone ever
run into a host that had both $_SERVER['path_translated'] and
$_SERVER{'documentRoot'] broke? I've seen $_SERVER{'documentRoot'] not
being correct, but has anyone seen it not correct and not having
$_SERVER['path_translated'] available? Previously, when I saw
$_SERVER['documentroot'] incorrect, I didn't know about
$_SERVER['path_translated'] so I don't know if it was good or not.

Looks like it'll work. Thanks. Maybe one day the people at PHP will
fix it so we don't have to work around it.

I believe you could get "x" to be 1, if you do this:

1. Set up a config_include_path.inc file in your DocumentRoot (possibly
virtual) directory.

2. Utilize $_SERVER['path_translated'] and $_SERVER{'documentRoot'] in all
the pages to temporarily set_include_path to your [virtual] DocumentRoot. 
If *those* are broken, you might as well just not use that host. :-^

3. In the config_include_path.inc, use set_include_path to set up whatever
you need to use for the new server/configuration.

So every page will set their include_path to DocumentRoot, then include a
file that from there that will change the include_path to whatever you
need for that particular server.

It's a bit of a hack, but cuts the number of config files to one (1) for a
transfer/install.

Hello Richard,

Friday, March 4, 2005, 11:41:29 AM, you wrote:
R> http://php.net/set_include_path


Ok... Maybe I should put all this together in one e-mail so that all
the issues can be looked at...

The problem:

Finding a reliable method to include files, keeping in mind the
following:

1. The site could be moved to a completely new host which could be of
   a different OS, and/or web server software, and could either be the
   one and only site on that host (dedicated server), or could be a
   virtual host (shared server).

2. The site could remain on the same host but is required to move to a
   new path. i.e. from htdocs/mysite to htdocs/mynewsite

3. The web host may or may not allow the use of .htaccess (Some Sambar
   configurations for example).

4. The method used would not affect any other virtual hosts. Meaning,
   the method used must be independent for each virtual host.

5. The method used would not utilize a folder where other virtual
   hosts could gain access to the included file (php.ini
   include_path).

6. The method (and this is the important one IMHO) would not require
   editing "x" number of pages in a site to change some static path
   that was set on each page.

7. The method used would not require a dedicated "include" file in
   every single folder of the site that could be included because it's
   in the same folder as the page needing it, because those would all
   have to be edited to fix the path if condition 1 or 2 was met.


Previously proposed solutions:

1. PHP.ini include_path
   This affects all virtual hosts and would require administrative
   overhead to prevent the owners of each virtual host from gaining
   access to other virtual host's include files. I suppose you could
   set it to something like: include_path="/php/includes" and have a
   separate subfolder under that for each virtual host. But since that
   folder is outside the web folder, there would have to be some
   mechanism (additional FTP account) for each person to gain access
   to their own include folder to add/edit/delete files in that
   folder. Then if the site is moved and they aren't using an
   include_path, you have to fix all your pages.

2. set_include_path
   This means if your site moves, you must edit "x" number of pages in
   the site to correct the path.

3. An include file in every directory to set the include path.
   You'd have to edit "x" number of these files to correct the path if
   the site moves. This would be much less work than the previous
   item, but it could be a lot of work on very big sites where you
   don't have shell accounts to do some scripted find/replace with.

4. Use the full URL to the file in the include statement.
   See item 2.

5. $_SERVER["DOCUMENT_ROOT"] and $_SERVER['PATH_TRANSLATED']
   Not always available or incorrect see
   mid:[EMAIL PROTECTED]


I may have missed some things, and if I've misunderstood how something
should work, then please let me know. I'm just looking for a more or
less foolproof method which doesn't require fixing code if the site is
moved. The closest I can come to it is the function I wrote but is a
pain because you have to put it in every page where you need an
included file. Granted, you only have to do it once, and then you're
done and a site move wont affect it, but it's still kludgy if you ask
me.

***

***

and then calling it as such:

include(dynRoot() . 'includes/db_connect.php');


I've had to move client sites between Sambar, Apache, IIS and Windows,
Linux. Most times I've had to go in and fix include paths because one
of the above solutions were originally used and wasn't viable on the
new host.

Thanks.

Right.. But if you're on a hosted server running Sambar which is
configured to ignore .htaccess, then what? (I'm not being facetious,
this is actually an issue I've run across for a client).

My point I guess, is that there should be a simple way in PHP to
reliably pull the DOC_ROOT for a virtual host that doesn't require
fixing "x" number of pages if you move the site to another server or
to another folder. PHP is great in terms of portability, but this
seems to be a major sticking point in making it less portable.

A webserver always knows where it is (i.e. external CSS declarations).

If path_translated exists use that as it indicates a virtual website,
otherwise use document_root
If I'm reading you correctly, then a truly transportable include might look like 
this:

$doc_root= (isset($_SERVER['path_translated'])? $_SERVER['path_translated'] : 	 
$_SERVER['document_root'];

I ran into the same problem and also asked here for any ideas.

I finally ended up writing my own function to do it. You can find the
tutorial here:

I'm still looking for a better way, cause this is kludgy.

1)  $_SERVER['DOCUMENT_ROOT']

2)  Check out phpinfo().  It will produce answers to this and MANY other 
questions for you in the future.

3)  Fix the clock/timezone on your computer.  Your messages are coming in

Well, the only way you'd be able to do that is by running PHP code local
to the server, and you'd only be able to do that once you're already
installed.

Makes more sense to just ask them - since there are all sorts of
possibilities with virtual hosts, etc.
