i have developed an application on Macintosh using MAMP
when i upload it to the server which is powered by Cpanel11, CentOS 5.. it gives several error regarding file permissions by default it gives 0700 file permission to most of the files which does not work within my server. i would want to know how do i apply the file permission settings for my PHP application,
the directory structure or the rule i want to apply is for the following conditions.
a)File uploading Directory
b) most of the php file is using include_once()
c) the normal php files which communicates with each other.
thank you
File uploads in PHP first hit the defined temporary directory (see 'upload_tmp_dir' directive in your PHP.ini) and finally your intended destination directory (PHP command "move_uploaded_file").
Your PHP process runs as a certain user that needs to own the destination directory or is in a group that is allowed to write to this directory - unless the whole directory is not writable for everyone (it's not in your case).
Try chmod after move_uploaded_file.

I have Ubuntu Server with lamp.
When i uploading files like xls or images it works fine, but when I trying to open it says me that the Excel file was broken. Same thing happens with images
Is it possible that php changes the file?
Permissions for /var/www/publick_html/uploads is 777
well, I know,I use windows and maybe this is extremely OFF TOPIC, but I have a simililar problem with uploaded files and my experience can be usefull for other people.
In my case, the uploaded file can not be open because it was written first in
C:\Windows\Temp
and then moved to the upload directory, but my temp folder doesn t have permission to access to it. Infact, if I click on temp folder I see:
After I clicked "Continue", the problem has been solved!
The problem was in versions of apache and php.
Version of apache was 2.2 and php was 5.4
I upgraded my apache to 2.4 version and now it works fine.
This should solve your problem with being unable to open uploaded files with PHP on SQL SERVER. It solved mine.
You may come across the following problem using PHP on Microsoft IIS: getting permission denied errors from the move_uploaded_file function even when all the folder permissions seem correct. I had to set the following to get it to work:
Write permissions on the the folder through the IIS management console.
Write permissions to IUSR_'server' in the folder's security settings.
Write permissions to "Domain Users" in the folder's security settings.
The third setting was required because my application itself lives in a secure folder - using authentication (either Basic or Windows Integrated) to identify the users. When the uploads happen IIS seems to be checking that these users have write access to the folder, not just whether the web server (IUSR_'server') has access.
Also, remember to set "Execute Permissions" to "None" in the IIS management console, so that people can't upload a script file and then run it. (Other checks of the uploaded file are recommended as well but 'Execute None' is a good start.)

I was trying to upload a custom logo to my drupal site which runs on IIS 8 with PHP.
I got the following upload error :
" Warning: move_uploaded_file(temporary://logo.png): failed to open stream: "DrupalTemporaryStreamWrapper::stream_open" call failed in drupal_move_uploaded_file() (line 1642 of C:\inetpub\wwwroot\drupalfull\includes\file.inc).
Warning: move_uploaded_file(): Unable to move 'C:\Windows\Temp\php25C3.tmp' to 'temporary://logo.png' in drupal_move_uploaded_file() (line 1642 of C:\inetpub\wwwroot\drupalfull\includes\file.inc).
File upload error. Could not move uploaded file."
Please help me. I have set both read and write permissions on IIS but still it does not work.
Create sites/default/files/tmp folder and give full permissions (777) and change 'Temporary directory' at admin/config/media/file-system.
I think it fixes yout problem.

If you are running ISS8 (web server) then the file path is different then the default for Unix.
Make sure you have the temporary folder setup correctly on your settings in Drupal and the folder has write permissions.
You can follow this article at step 5 and 6.
Create the folder:
Drupal uses the Sites\Default\Files directory to store temporary files and therefore must be able to write and modify files in this folder.
Create the folder:
C:\inetpub\wwwroot\Drupal>md sites\default\files
http://www.iis.net/learn/application-frameworks/install-and-configure-php-applications-on-iis/install-drupal-on-iis
Your problem is most likely the permission problem inside drupal. Since you are using windows system, you need to make sure the folder sites/default/files have writable permission for the IIS server. Config the permission to be writable for all user and see if it is working and then limit the permission step by step until you feel comfortable.
I'm going to put another answer in here because I guarantee I'm going to forget how I fixed it!
Basically, on Windows, the default upload folder for PHP is C:\Windows\Temp. As part of the Drupal upload, it moves files from the PHP upload folder to the Drupal Temporary//: folder. There is an issue however in PHP whereby the PHP executable needs read permission to the full path to the uploaded files, so C:\Windows\Temp. If this is not given, it will error out and the file will not be moved.
Details are at http://php.net/manual/en/function.realpath.php which is a function call made deep in Drupal's upload file code.
My fix was to create a folder elsewhere, say C:\PHPTemp, and modify PHP's settings (session.save_path and upload_tmp_dir) to point to this folder instead. After giving IIS_IUSRS full control (overkill? probably!), I was then able to upload images!
I've been tasked with sorting out a rather dated file upload script that uses move_uploaded_file()
I cannot for the life of me get it to actually upload the file to a directory unless it has 777s (obviously I know 777s are bad). The directory is owned by apache (in fact the whole httpdocs has been recursively chown-ed to apache:apache)... but the file still won't upload. The permissions are 755.
I've checked the apache configuration and the user and group are both correct (group: apache user: apache), and the file is 58kb so well within the max upload limit of the server.
PHP is running as FastCGI module.
Any ideas on what is causing this? Thanks.
This question is related to another question I wrote:
Trouble using DOTNET from PHP.
Where I was using the DOTNET() function in PHP to call a DLL I had written.
I was able to get it working fine by running php.exe example.php from the command line (with the DLL's still in the PHP folder).
I moved the php file to an IIS 7 webserver folder on the same machine (leaving the DLLs in the same php folder), but I keep getting a 500 internal service error.
I've checked the server logs (in c:\inetput\logs\ and in c:\windows\temp\php53errors) but there doesn't seem to be any relevant information about what caused the error. I even tried to change the php.ini settings to get more error feedback, but that doesn't seem to help.
I can only guess that the issue may be related to:
that php file not having the proper permissions (my dll does some file reading/writing)
php can't find the DLLs
The actual error I get is:
The FastCGI process exited unexpectedly.
Any idea on how to debug this problem?
The problem here is almost certainly related to file permissions.
When you run php.exe from the command line you run as your own logged-in user. When running a PHP script from IIS, in response to an http request, php.exe runs as a different user. Depending on your version of Windows it could be
IUSR_machine - on IIS6 and prior
IUSR on IIS7 and later
These users need permissions on the php file to be executed.
Read more about it
On IIS7 and later I use a command-line tool called icacls.exe to set the permissions on directories or files that need to be read by IIS and the processes it starts (like php.exe). This security stuff applies to all IIS applications: PHP, ASPNET, ASP-classic, Python, and so on.
IIS also needs to be able to read static files, like .htm, .js, .css, .jpog, .png files and so on. You can set the same permissions for all of them: Read and Execute.
You can grant permissions directly to the user, like this:
icacls.exe YOUR-FILE-GOES-HERE /grant "NT AUTHORITY\IUSR:(RX)"
You can also grant permissions to the group, to which IUSR belongs, like this:
icacls.exe YOUR-FILE-HERE /grant "BUILTIN\IIS_IUSRS:(RX)"
In either case you may need to stop and restart IIS after setting file-level permissions.
If your .php script reads and writes other files or directories, then the same user needs pernissions on those other files and directories. If you need the .php script to be able to delete files, then you might want
icacls.exe YOUR-FILE-HERE /grant "BUILTIN\IIS_IUSRS:(F)"
...which grants full rights to the file.
You can grant permissions on an entire directory, too, specifying that all files created in that directory in the future will inherit the file-specific permissions set on the directory. For example, set the file perms for the directory, then copy a bunch of files into it, and all the files get the permissions from the parent. Do this with the OI and CI flags (those initials stand for "object-inherit" and "container-inherit").
icacls.exe DIRECTORY /grant "BUILTIN\IIS_IUSRS:(OI)(CI)(RX)"
copy FILE1 DIRECTORY
copy FILE2 DIRECTORY
...
When I want to create a new vdir in IIS, to allow running PHP scripts, or ASPX or .JS (yes, ASP Classic) or Python or whatever, I do these steps:
appcmd.exe add app /site.name:"Default Web Site" /path:/vdirpath /physicalPath:c:\docroot
icacls.exe DIRECTORY /grant "BUILTIN\IIS_IUSRS:(OI)(CI)(RX)"
Then I drop files into the directory, and they get the proper permissions.
Setting the ACL (access control list) on the directory will not change the ACL for the files that already exist in the directory. If you want to set permissions on the files that are already in the directory, you need to use icacls.exe on the particular files. icacls accepts wildcards, and it also has a /t switch that recurses.
I have a PHP web application running on IIS, which allows a user to upload a file from a simple html form. The uploaded file is then moved to a folder on another server. This is working correctly on Apache, but fails on IIS with the error:
function['move_uploaded_file']failed to open stream: Permission denied
in...
I've checked all the permissions on the directories. If I run a simple PHP script through the command line to copy a file from the server into the folder on the other server it works correctly, so I suspect the problem is with IIS.
if (move_uploaded_file($_FILES ["file"] ["tmp_name"], "\\\\000.00.0.00\\tia\\web\\upload\\" .$_FILES["file"]["name"])) {
This has been covered already here. Quoting the reason here:
You have mapped target directory to a share such as \server2\files. These mappings are only available to the current users (eg, the admin account), not to the IUSR account that your php is probably running as (assuming IIS). Solution, don't use mappings, instead use the full 'unc' path name, ie '\server\share\folder\file.ext', also remember that the IUSR account will need access to these shares/folders/files
From what I can see in your comment, you are using a \\ prefixed network share as the target for your move_uploaded_file() operation.
I'll bet a beer that PHP isn't allowed to access that share. Remember, PHP runs with IIS's permissions!
Try saving to a local, globally writable path first. If that works, you know you have to fix the share's permissions.
