I have two folders
myappdemo.com/VueGuides/services/iclean
myappdemo.com/VueGuides/services/pics
I need to move iclean folder into pics folder using PHP.
Use rename(). Note that if this runs on a web server, the web server user must have access to write to the target directory.
rename("oldpath", "newpath");
// in your case, assuming the script calling rename()
// resides in the directory above 'myappdemo.com'
rename("myappdemo.com/VueGuides/services/iclean", "myappdemo.com/VueGuides/services/pics/iclean");
// Or use full absolute paths
rename("/path/myappdemo.com/VueGuides/services/iclean", "/path/myappdemo.com/VueGuides/services/pics/iclean");
There's a specific PHP function for it
http://php.net/manual/en/function.rename.php
If you are worried about SEO i recommend you using redirects 301 in your .htaccess.
That must be something like that:
RewriteRule ^/VueGuides/services/iclean http://myappdemo.com/VueGuides/services/pics [NS,R=301,L]
I required a different solution in my case as I was moving a sub folders contents into the parent folder. rename wouldn't work in my instance because the path was the same.
(For Linux based machines):
exec('mv '.$this->useFolder.'/'.$sub_folder.'/*'.' '.$this->useFolder);
This uses the inbuilt mv function through exec.

I'm creating a .php file that will be uploaded to the root directory of a server. I need that .php file to then figure out the path to the public_html folder or it's equivalent.
I need to do this because I want my .php file to be able to be uploaded to the root and used on any hosting account. Because many hosting companies use different file paths to the public_html folder or even call it something different, I'm trying to figure out how to detect it.
Preferable there is a server variable or easy test to do this. If not, the public_html folder will always contain a particular file so maybe I could search for this particular file and get the path that way. I'm just worried about a filename search being heavy on memory.
The .php file that is being executed is located inside the ROOT directory and needs to locate the public_html folder.
Like this: /home/user/file.php
needs to detect
/home/user/public_html/ or /home/user/var/www/ or /home/user/website.com/html/ etc.
The challenge with this is that a server can have very many public_html's so outside of the context of a request there is no real way to find out what that is.
One thing that you might be able to do to get this information from a php script (if you know the url to get to the host) is to create a php file called docroot.php that looks like this.
<?php
if ($_SERVER["REMOTE_ADDR"] == '127.0.0.1'){
echo $_SERVER["DOCUMENT_ROOT"];
}
Then within your file.php your would do something like
$docRoot = trim(file_get_contents("http://www.mydomain.com/docroot.php"));
This makes the assumption that the server can resolve to itself via the local interface by name.
I found this website which provided me with the only good solution I have found after scouring the web...
$root = preg_replace("!${_SERVER['SCRIPT_NAME']}$!", "", $_SERVER['SCRIPT_FILENAME']);
The way this works is by getting the full path of the file and then removing the relative path of the file from the full path.
I am writing installation script in PHP and part of my application may be installed in the folder that is one level above the public folder. Usually, public folder is called "public_html" but that may not always be the case. Is there some easy way to locate the name or path of the root public folder using PHP?
Try $_SERVER['DOCUMENT_ROOT']. (documentation)
If you want to get the directory above it, you can use dirname.
Brad does have a point, though; your script may not have access to that directory.
$_SERVER['DOCUMENT_ROOT'] will provide the full path up to public_html and you can explode with slash "/" and get last index of the exploded array.
You can also use realpath with argument "../", if you don't know the actual file name. This will return you the full parent path of public_html.
Hope one of this two will work for you :)
I'm needing to include a file from the parent directory, and other sub-directories, into a sub-directory. I've done it before by simply using include('/rootdirectory/file.php'); but now it won't seem to work.
Just wondering how I can do this, thanks.
Here's my exact line:
include('/forums/groups.php');
It's giving me this error(the page still runs):
Warning: include(/forums/groups.php) [function.include]: failed to
open stream: No such file or directory in
C:\xampp\htdocs\forums\blog\posts.php on line
Warning: include() [function.include]: Failed opening
'/forums/groups.php' for inclusion
(include_path='.;C:\xampp\php\PEAR') in
C:\xampp\htdocs\forums\blog\posts.php on line 3
include() and its relatives take filesystem paths, not web paths relative to the document root. To get the parent directory, use ../
include('../somefilein_parent.php');
include('../../somefile_2levels_up.php');
If you begin with a /, an absolute system file path will be used:
// Full absolute path...
include('/home/username/sites/project/include/config.php');
If your server is not resolving the file from the parent directory using
include '../somefilein_parent.php'
try this (using the parent directory relative to the script):
include __DIR__ . "/../somefilein_parent.php";
Here's something I wrote with that problem in mind:
<?
function absolute_include($file)
{
/*
$file is the file url relative to the root of your site.
Yourdomain.com/folder/file.inc would be passed as
"folder/file.inc"
*/
$folder_depth = substr_count($_SERVER["PHP_SELF"] , "/");
if($folder_depth == false)
$folder_depth = 1;
include(str_repeat("../", $folder_depth - 1) . $file);
}
?>
hope it helps.
Depends on where the file you are trying to include from is located.
Example:
/rootdir/pages/file.php
/someotherDir/index.php
If you wrote the following in index.php:
include('/rootdir/pages/file.php');it would error becuase it would try to get:
/someotherDir/rootdir/pages/file.php Which of course doesn't exist...
So you would have to use include('../rootdir/pages/file.php');
In laymans terms, and practicality, I see this as an old DOS trick/thing. Whoa! What was that? DOS? Never heard of it!
".." backs you out of the current sub-directory one time to a higher folder/directory, and .. enter typed twice backs you out too 2 higher parent folders. Keep adding the ".. enter" back to back and you will soon find yourself at the top level of the directory.
As for Newbies to understand this better, consider this (in terms of the home PC or "C:\ drive" if you know what that means, rather than the web-servers/host "root directory" ). While your at it, Consider your website existing somewhere on your home PC's hard drive, buried in some folder under the C:\ drive. Lastly, you can think of it as ".." is back one directory and "/" is forward one directory/folder.
Now!
If you are using the command prompt and are within the "myDocuments" folder of your PC you must back out of that folder to get closer to the higher directory "C:\" by typing the "../".
If you wanted to access a file that is located in the widows directory while you are still in the myDocuments folder you would theoretically type ../windows; in reality of DOS command prompt you would simply type .., but I am setting you up for the web. The / redirects forward to another directory naturally.
Using "myDocuments" lets pretend that you created 2 folders within it called "PHP1" and "PHP2", in such we now have the folders:
C:\myDocuments\PHP1
C:\myDocuments\PHP2
In PHP1 you place a file called index.php. and in PHP2 folder you placed a file called Found.php. it now becomes:
C:\myDocuments\PHP1\index.php
C:\myDocuments\PHP2\found.php
Inside the
C:\myDocuments\PHP1\index.php file you would need to edit and type something like:
<?php include ('../php2/found.php')?>
The ../ is positional thus it considers your current file location "C:\myDocuments\PHP1\index.php" and is a directive telling it to back out of PHP1 directory and enter or move forward into PHP2 directory to look for the Found.php file. But does it read it? See my thoughts on trouble shooting below.
Now! suppose you have 1 folder PHP1 and a sub-folder PHP2:
C:\myDocuments\PHP1\PHP2
you would simply reference/code
<?php include('/PHP2/found.php') ?>
as PHP2 exist as a sub-directory, below or within PHP1 directory.
If the above does not work it may have something to do with access/htaccess or permission to the directory or a typo. To enhance this...getting into trouble shooting...If the "found.php" file has errors/typo's within it, it will crash upon rendering at the error, such could be the reason (require/require_once) that you are experiencing the illusion that it is not changing directories or accessing the file.
At last thought on the matter, you may need to instantiate your functions or references in order to use the included/require "whatever" by creating a new variable or object such as
$newObject = new nameobject("origianlThingy");
Remember, just because you are including/requiring something, sometimes means just that, it is included/required to run, but it might need to be recreated to make it active or access it. New will surely re-create an instance of it "if it is readable" and make it available within the current document while preserving the original. However you should reference the newly created variable $newObject in all instances....if its global.
To put this in perspective of some web host account; the web host is some whopping over sized hard-drive (like that on your PC) and your domain is nothing more than a folder they have assigned to you. Your folder is called the root. Inside that folder you can do anything you are allowed to do.
your "one of many ways" to move between directories/folders is to use the ../ however many times to back out of your current in reference to folder position you want to find.
In my drunken state I realize that I know too much to be sane, and not
enough to be insane!"
Any path beginning with a slash will be an absolute path. From the root-folder of the server and not the root-folder of your document root. You can use ../ to go into the parent directory.
You may interest in using php's inbuilt function realpath().
and passing a constant DIR
for example:
$TargetDirectory = realpath(__DIR__."/../.."); //Will take you 2 folder's back
String realpath() :: Returns canonicalized absolute pathname ..
I took inspiration from frank and I added something like this in my "settings.php" file that is then included in all pages when there is a link:
"settings.php"
$folder_depth = substr_count($_SERVER["PHP_SELF"] , "/");
$slash="";
for ($i=1;$i<=($folder_depth-2);++$i){
$slash= $slash."../";
}
in my header.php to be included in all pages:
a href= .... php echo $slash.'index.php'....
seems it works both on local and hosted environment....
(NOTE: I am an absolute beginner )
Had same issue earlier solved like this :
include('/../includes/config.php'); //note '/' appearing before '../includes/config.php'
the root directory (in PHP) is the directory of the file that is pinged. For example, I go to http://localhost/directory/to/file/index.php, the root directory will be "/dictory/to/file", since it's the one that you've made a web request for.
I can't believe none of the answers pointed to the function dirname() (available since PHP 4).
Basically, it returns the full path for the referenced object. If you use a file as a reference, the function returns the full path of the file. If the referenced object is a folder, the function will return the parent folder of that folder.
https://www.php.net/manual/en/function.dirname.php
For the current folder of the current file, use $current = dirname(__FILE__);.
For a parent folder of the current folder, simply use $parent = dirname(__DIR__);.
If your configuration file PHP.ini is set up correctly then you can use:
include($_SERVER["DOCUMENT_ROOT"]."/my_script.php");
// or
require($_SERVER["DOCUMENT_ROOT"]."/my_script.php");
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
