I'm working on making my web app more portable but I'm having trouble with making links in a sub-directory root-relative.
/website - Let's say that's my directory for the website. /inc -
That's my includes directory for header, footer, and eventually my
config file.
Everything inside the website directory works fine.
I'm trying to include my header/footer files in a receipt directory with..
include("/website/inc/header.php");
but I get..
Warning: include(/website/inc/header.php): failed to open stream: No
such file or directory in F:\xampp\htdocs\website\receipt\index.php on
line 8
Warning: include(): Failed opening '/website/inc/header.php' for
inclusion (include_path='.;F:\xampp\php\PEAR') in
F:\xampp\htdocs\website\receipt\index.php on line 8
in my browser. I've tried removing the / and even adding localhost and htdocs (which was just a desperate attempt at getting it to work). What am I doing wrong and how can I correct it?
That's because a file path starting with / is treated as a file path starting from the root of file system. You have F:\ as a root that's why such a directory doesn't exist.
In your case you have to do something like ../../website/inc/header.php but that depends on the location of the folder where your script resists.
PHP (but not HTML!) works with whole file system, while HTML works only with the site's home directory.
By the way, such file paths are not allowed on Windows, they're only available on UNIX-like systems. If such a construction with /'s works on your server, that's strange as Windows has \ as path separator. Your code'll look like ..\..\website\inc\header.php. Note that you may need to escape the backslashes by adding another backslash like this \\

Sorry for you advanced guys, I'm actually teaching myself some PHP so this may seem like a beginner's question.
I'm using a testing server and then uploading to a remote server. The index.php file is located in "C:\XAMPP\htdocs\php_site" on my local pc and in "home/www/myname.atwebpages.com/" on the remote server. Now the code I'm trying to run is just a simple:
define ('ROOT', $_SERVER['DOCUMENT_ROOT']);
include ROOT."menu/menu.php";
This code works fine for the remote server. However, when attempted on my local machine, it spits out this error:
Warning: include(C:/XAMPP/htdocs/menu/menu.php): failed to open stream: No such file or directory in C:\XAMPP\htdocs\php_site\index.php on line 21
Clearly, it's not looking in the php_site folder. Instead, it's tying to find a menu folder in the htdocs directory, but it's not there. The menu folder is located inside the site folder, php_site. If I chance around the code to work on the local machine, it no longer works on the remote server. I'm a little confused as to how to get around this problem.
I think $_SERVER['DOCUMENT_ROOT'] is defined by apache, so you'd need to change the config there. Or, define the ROOT constant relative to where you actually put your files, so if you do something like:
define ('ROOT', dirname(__FILE__));
Put that in a constants file in the same folder as your index.php.
Your document root on the remote and local machines is different. On your local machine your document root is the htdocs directory, and the php_site folder is merely a sub-folder, and thus the path is wrong.
I suggest either making the ROOT directory be a relative directory to the index page, or have a constants file in the root directory of the PHP site that defines the root directory as the directory it is in (which would be in the php_site directory on your local machine, the same directory as your index page). define ('ROOT', dirname(__FILE)); would work in this situation.
Another idea is to use a try-catch to catch the failure of the include statement, and attempt to try another directory, perhaps using define ('ROOT', $_SERVER['DOCUMENT_ROOT']); first, and if it fails, attempt to use define ('ROOT', $_SERVER['DOCUMENT_ROOT'] . 'php_site/'); instead.
I want to move my data directory outside of the web root. I have file paths stored in my database and would like to be able to redirect looking for files through a symlink instead of having to change the saved paths.
Example, currently I have a structure like this:
/root/webroot/data/file.ext
And my database path will be: /root/webroot/data/file.ext as well. I'd like to move data outside of webroot so I have:
/root/data/file.ext
/root/webroot/data -> root/data
Where /root/webroot/data is a linux style symlink to root/data. I have set this up, but when I do a readfile on the previously stored path (/root/webroot/data/file.ext) it fails. I.e. I do this:
readfile('/root/webroot/data/file.ext');
I get back:
Warning: readfile(/root/webroot/data/file.ext) [function.readfile]: failed to open stream: No such file or directory in [file] on line ...
Is there anything I can do to help these paths resolve?
Note: The permissions of the folders and files all match. That of the symlink is root:root, from which it was created, but chown doesn't seem to work on it.
Where are you running the script from? If you are calling the directory without the leading slash:
readfile('root/webroot/data/file.ext');
then you better make sure it is running in the same directory root is sitting in. However, if you are running this from webroot, you will need to update the readfile path to something like:
readfile('data/file.ext');
I'm a total PHP noob and am using a pretty simple PHP include:
<?php include("~head.php"); ?>
to do a bit of templating for a website (to achieve common headers, footers, menus for all my pages).
NOTE: The tilde (~) is simply there to make the directories easier to look at (pushes main files to the top of the list when sorted alphabetically)
It's working great for files that are in the same directory but when I reference a file outside of a directory, like so:
<?php include("../~head.php"); ?>
However, it simply doesn't seem to be finding the file as the header is clearly not being pulled into the markup.
Conversely, if I reference the file with a full url, e.g.
<?php include("http://example.com/~head.php"); ?>
I get the following error code on my page.
Warning: include() [function.include]: URL file-access is disabled in the server configuration in /home/content/65/7392565/html/bikini/angela_bikini.php on line 1
Warning: include(http://example.com/~head.php) [function.include]: failed to open stream: no suitable wrapper could be found in /home/content/65/7392565/html/products/product_a.php on line 1
Warning: include() [function.include]: Failed opening 'http://example.com/~head.php' for inclusion (include_path='.:/usr/local/php5/lib/php') in /home/content/65/7392565/html/products/product_a.php on line 1
Strangely, the "../file.php" syntax works for non-header files (e.g. the include I'm using for the menu).
As such code's gotten to be a bit of a fragmented mess and is difficult to maintain changes across all the different pages. Any thoughts or solutions would be very much appreciated. I really am a noob tho so I probably won't be able to wrap my head around anything too fancy. : )
Thanks for your time.

Rather than using only the ../ to get the directory above, a construct like this will create the full filepath:
// Assuming you are including from the root
$application_path = dirname(__FILE__);
include("$application_path/../header.php);
Typically I'll do this by defining a constant, rather than using a variable.
define('APP_PATH', dirname(__FILE__));
Use this as:
// Assuming you are including at the file root:
define('APP_PATH', dirname(__FILE__));
include(APP_PATH . "/include/head.php");
// Assuming you are including from /include (one directory in)
// append a "/../" onto the end to indicate that the application
// root is one directory up from the currently executing file.
define('APP_PATH', dirname(__FILE__) . "/../");
include(APP_PATH . "somefile_at_the_root.php");
You have to be careful with the tilde! Under UNIX-like operating systems, the tilde is a shortcut to your home directory. If maybe the Apache server runs under the account www, your file-reference could be interpreted like this:
/home/www/head.php
And for the approach of using the full URL, the error says all:
URL file-access is disabled in the server configuration
Ignoring that it isn't best practice to use full URLs (because your folder structure could change etc.), you have to enable allow_url_include in your php.ini (see PHP.net).
If you really want to have your important files on top, you could use the underscore _.
I'm deploying from my WAMP testing environment to an online test...
Locally I had my include paths something like this:
include('C/wamp/www...')
how do i find the equivalent path on my server?
i've tried using '/' to get to the root but i get this error:
Warning:
require_once(/test123/mvc/views/txt/index_nav_txt.php)
[function.require-once]: failed to
open stream: No such file or directory

on line 37
You would actually need:
require_once("/home/codlife/public_html/test123/mvc/views/txt/index_nav_txt.php");
notice the edition of /home/codlife/public_html/
The initial / Takes you to the root of the server and your code is located inside /home/codlife/public_html/
do you mean
$_SERVER['DOCUMENT_ROOT']
which basically gives you the full path to your working website directory i.e. c:/wamp/www/(windows) or /var/www/vhost/domain.com/httpdocs/ (linux)
You should probably read up on include_path ( http://php.net/include_path ) - This is generally set to include the document root (where your website is) and can be altered so that you don't have to repeatedly include the same paths.
how do i find the equivalent path on my server?
You don't find it - you tell it where it should be. Admittedly this is not always practical when you buy a hosting package (which IME are usually badly supported and come with virtually no documentation).
First thing to note is regardless of where / how the code is hosted, you should always use paths relative to the directories configured on the php include path (or relative to the PHP script initially invoked by the browser request - the '.' entry from the include_path cited in the error) - never absolute paths. You can easily find this out with:
<?php
print ini_get('include_path');
?>
Judging from the path cited in the error message, it appears to be a POSIX system. The root of the filesystem as seen by the webserver might be quite different from the root as seen from your FTP or SSH software, but they are probably the same.
Note that if this is a shared host, then you probably won't have access to put files in /usr/lib/php or /usr/local/lib/php - so your only option is to use a relative path - which is going to get very messy -
You could do some clever coding around this - but do have a look at packages such as Dokuwiki and phpmyadmin to see how they organise the include files in a relocateable way without any dependance on manipulating the php.ini settings.
Alternatively you may be able to override the include_path via .htaccess, e.g.
php_value include_path ".:/home/codlife/public_html:/usr/lib/php:/usr/local/lib/php"
(which would set a base include_path to your document root)
HTH
C.
Use a configuration file where you store things like:
$application_root = '/home/code_life/public_html/';
In this file use all your environment specific variables or constants. When you deploy the application on a different machine, you just update configuration file.
Example:
You have in your root application a folder called settings with settings.php where you can define:
define('DIR_ROOT', dirname(dirname(__FILE__)) . '/');
Now, on every machine, the DIR_ROOT will be the root of your application and you don't have to change anything.
Warning: include(/2008/2009/assets/inc/base/error.inc.php) [function.include]:
failed to open stream: No such file or directory in
C:\Program Files\Apache Group\Apache2\htdocs\2008\2009\assets\inc\base\header.inc.php on line 82
I am receiving the above error when including a file on a WAMP setup. Is it possible that Windows is interpreting the /2008/ to mean c:/2008 rather than the actual http://localhost/2008?
To give a bit more detail, I have a constant defined as ROOT that I use all over my site. (ROOT in this instance is set to /2008/2009/). I use ROOT before paths for images, links, css files, include/require files, etc. The CSS and links are properly scaling to localhost/2008/2009, but include files are not being found.
Any help would be greatly appreciated.
PS php.ini has include path defined as:
include_path = C:\Program Files\Apache Group\Apache2\htdocs"
Update
I was using URL rewriting to change item/x to item-display.php?id=x, this change in folders is what ROOT was built off of. This made anything displayed to the browser (imgs, links, etc) all work flawlessly, but made anything internal not work, as item-display.php is actually one folder down. I moved item-display.php to an item folder, and this made the actions consistent both client side and server side.
You’re using an absolute path rather than a relative path.
If you are using the include path, you have to specify a relative URL, starting with the first directory or ./. Btw, you should define your path with something like dirname(__FILE__) in a file whose position in your project is not going to change or by looking into server. Otherwise, installing your application on another server is going to be unnecessarily complicated.
