how to include the file with relative path? - php

there is a file directory as this:magento\app\design\frontend\default\template\catalog\product\view.phtml
the another file directory as this:magento\blog\wp-blog-header.php
now,if i want to in view.phtml include the wp-blog-header.php.how do i do?thank you.
include('../../../../../../../wordpress/wp-blog-header.php');

You could use document root ("$_SERVER["DOCUMENT_ROOT"]"). But that only applies if your app is installed as the only app in the base directory on the web server. If you are running the app in a sub directory, that you need to adjust for that. However, this will make the app less portable as you cannot change the directory easily without having to modify codes.
Based on your example, it seems that you are running Magento, with Magento, you can use "Mage::getBaseDir" method to get the base directory of Magento and relative the include file from that.

Personally I would go from root up, not all of this ../../ jazz:
include($_SERVER['DOCUMENT_ROOT'] . "/path-to-include-file");
You sure the wordpress header is compatable with magento? Could face some horrible anomalies there.

That would work, you just have to count the slashes to make sure it's the same as before. However, you can also create a symbolic link in your magento\app\design\frontend\default\template\catalog\product\ directory that points to magento\blog\wp-blog-header.php.
ln -s magento\blog\wp-blog-header.php wp-blog-header.php would do the trick then you can just: include ("wp-blog-header.php");
You can also reference $_SERVER["DOCUMENT_ROOT"] in your include.

Include php files when they are in different folders

Most of my website is in my root directory. And In that directory there is "css", "functions", "images" folder. Everything works fine when I include php files within index.php or any other root file. It includes it fine and executes it fine.
But problem occurres when I made folder "blog". So this is totally new and separate root folder with CMS and its own "root" files. And I try to include css from main root directory or some php files from "functions" folder in main root directory, Everything breaks down. I know I have to include it as ../functions/myfile.com. But this files includes some other files so it just wont work properly and won't be able to include other files properly.
Is there any idea how to fix this problem?
You can get to the root from within each site using $_SERVER['DOCUMENT_ROOT']. For testing ONLY you can echo out the path to make sure it's working, if you do it the right way. You NEVER want to show the local server paths for things like includes and requires.
Site 1
echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/';
Includes under site one would be at:
echo $_SERVER['DOCUMENT_ROOT'].'/includes/'; // should be '/main_web_folder/includes/';
Site 2
echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/blog/';
The actual code to access includes from site1 inside of site2 you would say:
include($_SERVER['DOCUMENT_ROOT'].'/../includes/file_from_site_1.php');
It will only use the relative path of the file executing the query if you try to access it by excluding the document root and the root slash:
//(not as fool-proof or non-platform specific)
include('../includes/file_from_site_1.php');
Included paths have no place in code on the front end (live) of the site anywhere, and should be secured and used in production environments only.
Additionally for URLs on the site itself you can make them relative to the domain. Browsers will automatically fill in the rest because they know which page they are looking at. So instead of:
<a href='http://www.__domain__name__here__.com/contact/'>Contact</a>
You should use:
<a href='/contact/'>Contact</a>
For good SEO you'll want to make sure that the URLs for the blog do not exist in the other domain, otherwise it may be marked as a duplicate site. With that being said you might also want to add a line to your robots.txt file for ONLY site1:
User-agent: *
Disallow: /blog/
Other possibilities:
Look up your IP address and include this snippet of code:
function is_dev(){
//use the external IP from Google.
//If you're hosting locally it's 127.0.01 unless you've changed it.
$ip_address='xxx.xxx.xxx.xxx';
if ($_SERVER['REMOTE_ADDR']==$ip_address){
return true;
} else {
return false;
}
}
if(is_dev()){
echo $_SERVER['DOCUMENT_ROOT'];
}
Remember if your ISP changes your IP, as in you have a DCHP Dynamic IP, you'll need to change the IP in that file to see the results. I would put that file in an include, then require it on pages for debugging.
If you're okay with modern methods like using the browser console log you could do this instead and view it in the browser's debugging interface:
if(is_dev()){
echo "<script>".PHP_EOL;
echo "console.log('".$_SERVER['DOCUMENT_ROOT']."');".PHP_EOL;
echo "</script>".PHP_EOL;
}
If I understand you correctly, You have two folders, one houses your php script that you want to include into a file that is in another folder?
If this is the case, you just have to follow the trail the right way.
Let's assume your folders are set up like this:
root
includes
php_scripts
script.php
blog
content
index.php
If this is the proposed folder structure, and you are trying to include the "Script.php" file into your "index.php" folder, you need to include it this way:
include("../../../includes/php_scripts/script.php");
The way I do it is visual. I put my mouse pointer on the index.php (looking at the file structure), then every time I go UP a folder, I type another "../" Then you have to make sure you go UP the folder structure ABOVE the folders that you want to start going DOWN into. After that, it's just normal folder hierarchy.
i had the same issue and found a code on https://css-tricks.com/php-include-from-root/ that fixed it
<?php
$path = $_SERVER['DOCUMENT_ROOT'];
$path .= "/common/header.php";
include_once($path);
?>
None of the above answers fixed this issue for me.
I did it as following (Laravel with Ubuntu server):
<?php
$footerFile = '/var/www/website/main/resources/views/emails/elements/emailfooter.blade.php';
include($footerFile);
?>
Try to never use relative paths. Use a generic include where you assign the DocumentRoot server variable to a global variable, and construct absolute paths from there. Alternatively, for larger projects, consider implementing a PSR-0 SPL autoloader.

Is it a good idea to use $_SERVER['DOCUMENT_ROOT'] in includes?

Is this, for example, a good idea?
require_once($_SERVER['DOCUMENT_ROOT'].'/include.php');
If you have two virtual hosts on the same server, one for live and one for development, with different Apache DocumentRoots, this would avoid having to include absolute paths when the source of the include is unknown, and may be in any directory.
(Note: file paths in the following section are relative to the web root. They would in fact be like /var/www/app/core/init.php, where /var/www/app is the web root)
For instance: I have an /core/init.php which is called using relative paths from places all over the website (/file.php, /dir/file.php or /dir/dir/file.php).
This init.php then includes several function pages, in the fund directory, a subdir of /core (as in /core/func/userfunctions.php).
So, in init.php, I can use the $_SERVER method, because it breaks if I use a relative path and try to call functions from a page like /dir/file.php.
I can't see any problem with it, but in general what could go wrong?
I've seen cases where $_SERVER['DOCUMENT_ROOT'] is not set or is not what you would expect (i.e. not set in CLI or old IIS, or invalid in certain CGI setups).
For that reason you can use dirname(__FILE__) to obtain the path of the script that line is called in. You can then reference relative paths from there e.g.
include dirname(__FILE__) . '/../../other/file.php';
I go with the above method when the directory structure of the files is known and is not subject to change.
If DOCUMENT_ROOT is not available, the following is a suitable replacement:
substr($_SERVER['SCRIPT_FILENAME'], 0, -strlen($_SERVER['SCRIPT_NAME']));
You don't need to do this. PHP looks for the included file in the document root by default.
You can use set_include_path($new_include_path) to change this behaviour, or edit include_path in the php config file.
Also, from http://php.net/manual/en/reserved.variables.server.php:
'DOCUMENT_ROOT'
The document root directory under which the current script is executing, as defined in the server's configuration file.
For example, if you use URL rewriting, you will be very happy when you find out that the includes in your /there/are/so/many/paths/in/the/url/of/this/ page are still working!

How to declare paths in PHP to allow easy app move to not rooted folder?

I have wamp setup on my windows box. Generally, when I bring a site down from the web, I create a folder inside my www folder for the site name. ex: c:\wamp\www\mysite. Once I have the folder, I copy down all the live files. The issue is that all the paths are then broken because my local folder isn't rooted.
What is the best way to setup paths so that if the site moves to a folder that isn't rooted, it will work easily?
I use a file (usually called something like config.php) to keep track of the root folder. My definitions (constants) look like this:
define('BASE_DIR','/wherever/whenever/');
define('LIB_DIR', BASE_DIR . 'lib/');
And then when you need to include a file
include LIB_DIR . 'aFile.php';
This would be something you do on a new site or if you have time to refactor your current site.
Create an include file, that has constants setup based upon whatever the root directory is... then in your code, use the constants you created to include files.
Also note, that when you are using directory "slashes", always use the build in constant DIRECTORY_SEPARATOR instead of hard coding it, this will allow you to go from WIndows to Linux seamlessly.
We use $_SERVER['DOCUMENT_ROOT'] to determine where we are in the filesystem and then simply append the folder name of our project to that. This works perfectly for us. You should always use a configuration.php where you define basic paths and URL's that may change when moving the project from one server/folder to another.
Option 1. Use <base href=""/> tag
Option 2. Use a config file, like #MattCan suggests
Option 3. Use a server environment variable, like #Bjorn suggests
Option 4. Create a virtual host on your apache, than you can create a domain who appoint exactly where are your app folder. Apache Doc here

how to use config file from a subdirectory while it is been kept at root directory in PHP

I am developing a web application. contents are:
root dir (/var/www/)
config.php
index.php
details.php
admin dir (/var/www/admin)
admin.php
I have included config.php file into index.php, details.php in root directory using require_once('config.php') as this file contains database passwords, styles, images directory paths..
how can i include that config files in my admin/admin.php file so that one config file can be used in anywhere(even in subdirectories) of my web application. Will it make any difference for the value of define('APP_BASE_PATH', dirname(__FILE__)); when same config file is used by all files in the web application.
if i am wrong somewhere then please get me right.
If your server properly configured, just
include $_SERVER['DOCUMENT_ROOT']."/config.php";
anywhere
You have also 2 other possible ways.
a Front controller setup, where ALL user requests going into one file. And ths one going to include all others from their subdirectories. Personally I don't like it cause this front file become a mess. Though it's widely used.
I decided not to mention it because noone would use a hardcoded full path anyway.
Update after clarification in comments: You are looking for a way to include a central configuration file from anywhere in your project's folder structure.
#Col. Shrapnel shows one way, DOCUMENT_ROOT. It's the only way to use an "absolute" path from a nested folder structure. It has the limitation I describe above, but it's fine otherwise.
If you want maximum portability (i.e. the possibility to run the app with e.g. www.example.com/myapp/version_1 as its root directory), you would have to use relative references from within your folder structure to "climb down" to the config file, e.g. ../../config.php that will work reliably too, although be a bit cumbersome e.g. if you move a script to a different folder and you have to update the relative path.
you can use the same config file every time... using "/" will take you back to the root directory... so in admin/admin.php use this:
require_once("/config.php");
you can use "../" to take you up one directory eg:
require_once("../config.php");
was this what you were looking for?

PHP: Include file from different root directory

I have 2 root directories for a site, httpdocs and httpsdocs. I am sure its obvious what the 2 are for. But I want to keep things consistent through-out the site like global navigation. Right now I have two separate files for this (one in each side) and I would like to only have one. This is hard to maintain because each time I change one I have to change the other (if I remember to), it breaks the DRY rule. But if I try to include a file from one side to the other using a relative path it tells me the file path is not allowed because it goes outside the document root. If I try to include it with an absolute URL I get another error saying file access is disabled in the server configuration. (I am on a hosting account so the most I can change as far as server config is limited to .htaccess). So can anyone think of a work-around for this?
Why not put your global include file in yet another directory (lets call it library) and then have each http root have an include file that includes ../library/lib.php, then sets specific paramaters. This gives you the added benifit of your library php files not being in the document root path as well.
And actually. Updating because I just read the entry about "relative path" issues.
Could you set the "include path" php value to include that directory?
Something like this:
ini_set('include_path', realpath(dirname(__FILE__)."/../library").":".ini_get('include_path'));
require_once('lib.php');
Did a little more research - seems that changing open_basedir is not possible unless you are able to edit the httpd.conf or php.ini values. PHP Manual: open_basedir
Do you have the ability to create symbolic links between the two directories?
