I am trying to write a query to a file for debugging. The file is in database/execute.php. The file I want to write to is database/queries.php.
I am trying to use file_put_contents('queries.txt', $query)
But I am getting
file_put_contents(queries.txt) [function.file-put-contents]:
failed to open stream: Permission
denied
I have the queries.txt file chmod'd to 777, what could the issue be?
Try adjusting the directory permissions.
from a terminal, run chmod 777 database (from the directory that contains the database folder)
apache and nobody will have access to this directory if it is chmodd'ed correctly.
The other thing to do is echo "getcwd()". This will show you the current directory, and if this isn't '/something.../database/' then you'll need to change 'query.txt' to the full path for your server.
You can make Apache (www-data), the owner of the folder:
sudo chown -R www-data:www-data /var/www
that should make file_put_contents work now. But for more security you better also set the permissions like below:
find /var/www -type d -print0 | xargs -0 chmod 0755 # folder
find /var/www -type f -print0 | xargs -0 chmod 0644 # files
change /var/www to the root folder of your php files
There's no need to manually write queries to a file like this. MySQL has logging support built in, you just need to enable it within your dev environment.
Take a look at the documentation for the 'general query log'.
This can be resolved in resolved with the following steps :
1. $ php artisan cache:clear
2. $ sudo chmod -R 777 storage
3. $ composer dump-autoload
Hope it helps
I know that it is a very old question, but I wanted to add the good solution with some in depth explanation. You will have to execute two statements on Ubuntu like systems and then it works like a charm.
Permissions in Linux can be represented with three digits. The first digit defines the permission of the owner of the files. The second digit the permissions of a specific group of users. The third digit defines the permissions for all users who are not the owner nor member of the group.
The webserver is supposed to execute with an id that is a member of the group. The webserver should never run with the same id as the owner of the files and directories. In Ubuntu runs apache under the id www-data. That id should be a member of the group for whom the permissions are specified.
To give the directory in which you want to change the content of files the proper rights, execute the statement:
find %DIR% -type d -exec chmod 770 {} \;
.That would imply in the question of the OP that the permissions for the directory %ROOT%/database should be changed accordingly. It is therefor important not to have files within that directory that should never get changed, or removed. It is therefor best practice to create a separate directory for files whose content must be changed.
Reading permissions (4) for a directory means being able to collect all files and directories with their metadata within a directory. Write permissions (2) gives the permission to change the content of the directory. Implying adding and removing files, changing permissions etc.. Execution permission (1) means that you have the right to go into that directory. Without the latter is it impossible to go deeper into the directory. The webserver needs read, write and execute permissions when the content of a file should be changed. Therefor needs the group the digit 7.
The second statement is in the question of the OP:
find %DOCUMENT_ROOT%/database -type f -exec chmod 760 {} \;
Being able to read and write a document is required, but it is not required to execute the file. The 7 is given to the owner of the files, the 6 to the group. The webserver does not need to have the permission to execute the file in order to change its content. Those write permissions should only be given to files in that directory.
All other users should not be given any permission.
For directories that do not require to change its files are group permissions of 5 sufficient.
Documentation about permissions and some examples:
https://wiki.debian.org/Permissions
https://www.linux.com/learn/tutorials/309527-understanding-linux-file-permissions
http://www.linux.org/threads/file-permissions-chmod.4094/
Gathering info from this link stackoverflow-image save doesn't work with chmod 777 and from user azerafati and Loek Bergman
if you were to look under /etc/apache/envvars file you will see something like:
export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data
Apache is run under the username 'www-data'
'0755' means the file owner can read/write/execute but group and other users cannot write. so in ur terminal, cd to the folder containing your 'images' folder. then type:
find images -type d -exec chmod 0755 {} \;
find images -type f -exec chmod 0755 {} \;
sudo chown -R www-data:www-data images
you must change persmissions first before changing owner.
enter your password when prompted. this will make 'www-data' owner of the images folder.
your upload should now work.
I use a shared Linux hosting, when my admin changed the php to 5.3 I got many errors for the "file_put_contents" code. try to test my plan:
In your host create a file like mytest.php, and put this code in and save:
<?php mail('Your-EMail','Email-Title','Email-Message'); ?>
Open the URL "www.your-domain.com/mytest.php" one time and then check your email. You should have an email from your host with the information you entered in mytest.php, check the sender name. If it's from Nobody you have problem about "Permission Denied" because something not defined and if the sender name is like my id: iietj8qy#hostname5.netly.net you don't have a problem.
My admin changed the server and installed the host again I think and the problem got solved, tell your host administration what I told you and maybe they find the answer.
If you are pulling from git from local to server, you will need to clear cache sometimes because of the view files it gets uploaded with it / or other cached files .
php artisan cache:clear
Sometimes it might just to the trick if your application was working before the git pull
this might help. It worked for me. try it in the terminal
setenforce 0
For anyone using Ubuntu and receiving this error when loading the page locally, but not on a web hosting service,
I just fixed this by opening up nautilus (sudo nautilus) and right click on the file you're trying to open, click properties > Settings > and give read write to 'everyone else'
use this cammand to give permission for storage/framework and logs
sudo chmod -R 777 storage/logs storage/framework
if you still have a permission error
try this to give group to write in log
sudo chmod g+w storage/logs
had the same problem; my issue was selinux was set to enforcing.
I kept getting the "failed to open stream: Permission denied" error even after chmoding to 777 and making sure all parent folders had execute permissions for the apache user. Turns out my issue was that selinux was set to enforcing (I'm on centos7), this is a devbox so I turned it off.
I ran into the same issue, I'm using Laravel, so what I just did was:
php artisan view:clear
And fixed!
I stopped the virus scanner (Avast). That solved the problem! It eventually appeared that Avast had a ransomware shield blocking the write actions to the documentroot folder(s). Adding the shield exceptions for the individual programs (PHP, Tesseract) solved the issue!
Here the solution.
To copy an img from an URL.
this URL: http://url/img.jpg
$image_Url=file_get_contents('http://url/img.jpg');
create the desired path finish the name with .jpg
$file_destino_path="imagenes/my_image.jpg";
file_put_contents($file_destino_path, $image_Url)
There 2 way to resolve this issues
1. use chmod 777 path-to-your-directory.
if it does not work then
2. simply provide the complete path of your file query.txt.
Furthermore, as said in file_put_contents man page in php.net, beware of naming issues.
file_put_contents($dir."/file.txt", "hello");
may not work (even though it is correct on syntax), but
file_put_contents("$dir/file.txt", "hello");
works. I experienced this on different php installed servers.

I'm trying to use PHP to create a file, but it isn't working. I am assuming this is because it doesn't have write access (it's always been the problem before). I tried to test if this was the problem by making the folder chmod 0777, but that just ended up making every script in that directory return a 500 error message until I changed it back.
How do I give PHP write access to my file system so it can a create a file?
Edit: It is hosted on Hostgator shared hosting using Apache.
Edit 2: Someone asked for the code:
The code is a GD image script. I know the rest of it works as previously I was creating the image every ime it was called. Now I am trying to create them when new text is added and save them to a folder. The write line I have is:
imagejpeg(null,$file,85);
I also created a test file to check if it was just a broken script (mainly copied from tizag):
http://gearboxshow.info/rkr/lesig.jpg/testfile.txt (I don't know if/how to post the code here properly. Here is the contents of the PHP script, minus PHP tags.)
It returns 13,13,1 (separate lines), so it looks as if it thinks it wrote something, but the testfile.txt is blank (I uploaded a blank one), or non-existent (if I delete it).
Edit 3: The server runs CentOS.
An easy way is to let PHP create the directory itself in the first place.
<?php
$dir = 'myDir';
// create new directory with 744 permissions if it does not exist yet
// owner will be the user/group the PHP script is run under
if ( !file_exists($dir) ) {
mkdir ($dir, 0744);
}
file_put_contents ($dir.'/test.txt', 'Hello File');
This saves you the hassle with permissions.
Simple 3-Step Solution
Abstract: You need to set the owner of the directory to the user that PHP uses (web server user).
Step 1: Determine PHP User
Create a PHP file containing the following:
<?php echo `whoami`; ?>
Upload it to your web server. The output should be similar to the following:
www-data
Therefore, the PHP user is www-data.
Step 2: Determine Owner of Directory
Next, check the details of the web directory via the command line:
ls -dl /var/www/example.com/public_html/example-folder
The result should be similar to the following:
drwxrwxr-x 2 exampleuser1 exampleuser2 4096 Mar 29 16:34 example-folder
Therefore, the owner of the directory is exampleuser1.
Step 3: Change Directory Owner to PHP User
Afterwards, change the owner of the web directory to the PHP user:
sudo chown -R www-data /var/www/example.com/public_html/example-folder
Verify that the owner of the web directory has been changed:
ls -dl /var/www/example.com/public_html/example-folder
The result should be similar to the following:
drwxrwxr-x 2 www-data exampleuser2 4096 Mar 29 16:34 example-folder
Therefore, the owner of example-folder has successfully been changed to the PHP user: www-data.
Done! PHP should now be able to write to the directory.
Set the owner of the directory to the user running apache. Often nobody on linux
chown nobody:nobody <dirname>
This way your folder will not be world writable, but still writable for apache :)
1st Figure out which user is owning httpd process using the following command
ps aux | grep httpd
you will get a several line response like this:
phpuser 17121 0.0 0.2 414060 7928 ? SN 03:49 0:00 /usr/sbin/httpd
Here 1st column shows the user name. So now you know the user who is trying to write files, which is in this case phpuser
You can now go ahead and set the permission for directory where your php script is trying to write something:
sudo chown phpuser:phpuser PhpCanWriteHere
sudo chmod 755 PhpCanWriteHere
You can change the permissions of a folder with PHP's chmod(). More information on how to use the command is here: http://php.net/manual/en/function.chmod.php
If you get a 500 Error when setting the permissions to 777 (world writable), then it means your server is setup to prevent executing such files. This is done for security reasons. In that case, you will want to use 755 as the highest permissions on a file.
If there is an error_log file that is generated in the folder where you are executing the PHP document, you will want to view the last few entries. This will give you an idea where the script is failing.
For help with PHP file manipulation, I use http://www.tizag.com/phpT/filewrite.php as a resource.
I found out that with HostGator you have to set files to CMOD 644 and Folders to 755. Since I did this based on their tech support it works with HostGator
I had the same problem:
As I was reluctant to give 0777 to my php directory, I create a tmp directory with rights 0777, where I create the files I need to write to.
My php directory continue to be protected. If somebody hackes the tmp directory, the site continue to work as usual.
You can set selinux to permissive in order to analyze.
# setenforce 0
Selinux will log but permit acesses. So you can check the /var/log/audit/audit.log for details. Maybe you will need change selinux context. Fot this, you will use chcon command. If you need, show us your audit.log to more detailed answer.
Don't forget to enable selinux after you solved the problem. It better keep selinux enforced.
# setenforce 1
Best way in giving write access to a directory..
$dst = "path/to/directory";
mkdir($dst);
chown($dst, "ownername");
chgrp($dst, "groupname");
exec ("find ".$dst." -type d -exec chmod 0777 {} +");
chmod does not allow you to set ownership of a file. To set the ownership of the file you must use the chown command.
I'm running Ubuntu, and as said above nobody:nobody does not work on Ubuntu. You get the error:
chown: invalid group: 'nobody:nobody'
Instead you should use the 'nogroup', like:
chown nobody:nogroup <dirname>
Tiny little hint!
echo whoami;
make sure you use BACK QUOTES
NOT
single quotes ' '
!
(of course now the back quotes don't show up in this editor! oh well, I tried!)
So I have a PHP file located in /var/www/html/test.php and I have it run the code shell_exec('touch /home/pi/Desktop/test_file')
However, the webpage displays fine but when I check the apache log files, I always get permission denied. I understand that apache is running as www-data user and my main user pi probably have some permission clash (I'm new to this stuff).
I tried many options I found on-line, the most promising was here, which suggested I run the commands:
sudo chown -R pi:www-data /home/pi/Desktop
sudo chmod -R g+s /home/pi/Desktop
...but I still get permission denied. Can anyone please suggest what permissions I may need to still configure? I want to ensure security, but at the same time need my PHP file to be able to create new files. I used the Desktop as an example directory, but really I don't care which directory, I just need a directory. I tried touching a file within /var/www/html, but that was permission denied as well. Thanks!
if your apache process is running as www-data, and the file ownership is pi:www-data, you probably need to run this chmod:
sudo chmod -R g+w /home/pi/Dekstop
First, setting the group as www-data won't matter if the files are not group writable. Mode 755 will ensure apache can read the files, but the www-data user would still not be able to write.
Secondly, using "g+w" adds group write without messing with any of the other bits. [644 becomes 664, and 755 becomes 775)]. This way you can safely adjust permissions recursively, without making files executable that shouldn't be.
Incidentally, sudo chmod g+s ... is probably not what you want. That will instead set the sgid bit, and not the group write bit.
First of all, why the heck are you using shell_exec to create a file? PHP has it's own touch() function that will do that for you. You can also create files just by opening a nonexistent file using certain modes (ie, fopen("myfile", "w"))
Using exec to create your files is surely messing with your permissions.
You need to find out which user PHP is running as and chown to that user. You can find that out by running get_current_user().
Then you need to change the permissions with chmod. There's an example in the comments so I won't repeat it. Good luck. Stop using shell_exec.
I created a project with Laravel 4 but when I go to the folder localhost /my_project/public get some errors related to the permissions. I solved it setting to 777 all the permissions of the folder and files contained in my_project. Is there a way to solve this thing is not to make 777?
What's happen when you set 755 permission to my_project directory? Try to change permissions and check it. Your directory should be able to read all files in public directory.
I set my ownership to be owned by www-data:
chown -R auser:www-data /path/to/laravel/root
I also make all my subfolders and files read and write by group:
chmod -R g+rw /path/to/laravel/root
I also make my folders have a sticky bit so if you add a new file, it inherits:
chmod -R g+s /path/to/laravel/root
This has always worked for me. Perhaps Linux experts might have better ideas but this is what I use.
Please refer to Laravel's documentation about installation located at http://laravel.com/docs/installation. Under no circumstances you should run laravel on production with full permissions to the whole world. You must also remember that your "application" will be executed from the public directory so there is NO reason to allow read/write/execute for the whole world to the whole project directory unless you don't care about security at all.
Anyway, extracted from Laravel's documentation from the permissions section:
"Laravel may require one set of permissions to be configured: folders
within app/storage require write access by the web server."
This whould make your project run smooth.
I am trying to write a query to a file for debugging. The file is in database/execute.php. The file I want to write to is database/queries.php.
I am trying to use file_put_contents('queries.txt', $query)
But I am getting
file_put_contents(queries.txt) [function.file-put-contents]:
failed to open stream: Permission

I have the queries.txt file chmod'd to 777, what could the issue be?
Try adjusting the directory permissions.
from a terminal, run chmod 777 database (from the directory that contains the database folder)
apache and nobody will have access to this directory if it is chmodd'ed correctly.
The other thing to do is echo "getcwd()". This will show you the current directory, and if this isn't '/something.../database/' then you'll need to change 'query.txt' to the full path for your server.
You can make Apache (www-data), the owner of the folder:
sudo chown -R www-data:www-data /var/www
that should make file_put_contents work now. But for more security you better also set the permissions like below:
find /var/www -type d -print0 | xargs -0 chmod 0755 # folder
find /var/www -type f -print0 | xargs -0 chmod 0644 # files
change /var/www to the root folder of your php files
There's no need to manually write queries to a file like this. MySQL has logging support built in, you just need to enable it within your dev environment.
Take a look at the documentation for the 'general query log'.
This can be resolved in resolved with the following steps :
1. $ php artisan cache:clear

For help with PHP file manipulation, I use http://www.tizag.com/phpT/filewrite.php as a resource.
I found out that with HostGator you have to set files to CMOD 644 and Folders to 755. Since I did this based on their tech support it works with HostGator
I had the same problem:
As I was reluctant to give 0777 to my php directory, I create a tmp directory with rights 0777, where I create the files I need to write to.
My php directory continue to be protected. If somebody hackes the tmp directory, the site continue to work as usual.
You can set selinux to permissive in order to analyze.
# setenforce 0
Selinux will log but permit acesses. So you can check the /var/log/audit/audit.log for details. Maybe you will need change selinux context. Fot this, you will use chcon command. If you need, show us your audit.log to more detailed answer.
Don't forget to enable selinux after you solved the problem. It better keep selinux enforced.
# setenforce 1
Best way in giving write access to a directory..
$dst = "path/to/directory";
mkdir($dst);
chown($dst, "ownername");
chgrp($dst, "groupname");
exec ("find ".$dst." -type d -exec chmod 0777 {} +");
chmod does not allow you to set ownership of a file. To set the ownership of the file you must use the chown command.
I'm running Ubuntu, and as said above nobody:nobody does not work on Ubuntu. You get the error:
chown: invalid group: 'nobody:nobody'
Instead you should use the 'nogroup', like:
chown nobody:nogroup <dirname>
Tiny little hint!
echo whoami;
make sure you use BACK QUOTES
NOT
single quotes ' '
!
(of course now the back quotes don't show up in this editor! oh well, I tried!)
