**I have tried permissions but still getting this error
Array ( [0] => sh: 1: /var/www/nodejs/tmp: Permission denied )
The command is execute from the route file of Laravel(MVC PHP Web application)
Tried CHMOD 777 , CHMOD +x etc.
My current permission is as follows
-rwxr-xr-x 1 root root *number* Oct 9 21:35 test.js
What did i not do?
My php code
$user_input = "http://google.com/";
putenv("PHANTOMJS_EXECUTABLE=/usr/local/bin/phantomjs");
exec('/var/www/nodejs/tmp test.js $user_input 2>&1',$output);
print_r($output);
Your test.js may be a script
In that case make sure the interpreter is also executable
another possibility is that your file is on a filesystem with no execute permissions
If test.js resides in directory /var/www/nodejs/tmp, they are not to be separated by space, but joined by slash:
exec('/var/www/nodejs/tmp/test.js $user_input 2>&1', $output);

I'm new to PHP and just faced the problem with creating and opening a file with fopen(). Here is my code:
<?php
$new_file = fopen('file.txt', 'w') or die("Cannot create a file");
$text = <<<_END
Line 1
Line 2
Line 3
_END;
fwrite($new_file, $text) or die('Cannot write to the file');
fclose($new_file);
When I try to run the file by opening it in the browser I see the next message: 'Cannot create a file'. But when I start debug session everithing works as it supposed to. I suspect that there is some issue with permissions and XDebug uses root access unlike the usual interpreter?
to write and read permission
chown -R www-data:www-data /var/www/dicrctoy
chmod -R 775 /var/www/dicrctoy
I have tested in my local environment no error was found
if you're using mac you should check the file permission
use chmod command to change permission
What is the meaning of chmod 777?
readable, writable and executable
Setting 777 permissions to a file or directory means that it will be readable, writable and executable by all users
To solve this problem first of all I was needed to check PHP user with the next command:
<?php echo `whoami`; ?>
It outputs:
www-data
This is the default PHP user. Next I checked the owner of the folder with this command:
ls -dl /var/www/html/test
It outputs:
drwxrwxr-x 2 username username 4096 Jun 26 12:49
Next I've sat permissions to the PHP user by running:
sudo chown -R www-data /var/www/html/test
Checking once again if the owner changed
ls -dl /var/www/html/test
And now it outputs
drwxrwxr-x 2 www-data username 4096 Jun 26 12:55
Done. Now I'm able to create and write to the file.
I am working on apache sever and generating some tmpdir using follwoing code.
$tmpdatadir = "/home/user/tmpdata/".$id."/";
if (mkdir($tmpdatadir)) {
/* do something */
}
dir created:
drwxr-xr-x 2 www-data www-data 4096 Aug 30 17:16 147257020639481
but when i try to write some data using
exec ("cat file.txt >". $tmpdatadir."sample.txt")
i get following error message.
permission denied. As i copy file as user:user so how can i change permision of directory. I found chown does this but i am not sure how can i change ownership of whole directory.
First of all, please review the permissions for www-data folder with ls /lrt, is that way you can see if your user is able to write on the file.
Then, you can use the command: chmod 666 www-data to change the permission of the file to read and write for all users, in this link you can find the syntax for chmod command and a useful calculator if you want limit other users.
Also I share with you the specific functions for commands chown and chmod. See this site.
I'm running XAMPP 1.8.2 with the default PHP 5.4.19 on OS X 10.8.5.
My PHP application is supposed to have read/write access to a certain local directory, but it's not working. For testing, I distilled it down to a very simple script:
<?php
$file = "/Volumes/RAID/AT_RISK/copra/uploadedfiles/file.txt";
$current = "hello world\n";
file_put_contents($file, $current);
?>
Warning: file_put_contents(/Volumes/RAID/AT_RISK/copra/uploadedfiles/file.txt): failed to open stream: Permission denied in /Applications/XAMPP-1.8.2/xamppfiles/htdocs/filetest.php on line 4
I've tried this command, but it doesn't help.
sudo chmod -R 777 /Volumes/RAID/AT_RISK/copra/
Here you can see the permissions for yourself:
$ pwd
/Volumes/RAID/AT_RISK/copra/uploadedfiles
$ ls -l
total 32
-rwxrwxrwx 1 elliott staff 7 Oct 12 22:31 file.txt
Silly me. Although the folder had correct permissions, the volume itself (/Volumes/RAID) was 700. Problem solved.
So, I have this error:
Warning: fopen(/path/to/test-in.txt) [function.fopen]: failed to open stream: Permission denied
Performing ls -l in the directory where test-in.txt is produces the following output:
-rw-r--r-- 1 $USER $USER 1921 Sep 6 20:09 test-in.txt
-rw-r--r-- 1 $USER $USER 0 Sep 6 20:08 test-out.txt
In order to get past this, I decided to perform the following:
chgrp -R www-data /path/to/php/webroot
And then did:
chmod g+rw /path/to/php/webroot
Yet, I still get this error when I run my php5 script to open the file. Why is this happening? I've tried this using LAMP as well as cherokee through CGI, so it can't be this.
Is there a solution of some sort?
Edit
I'll also add that I'm just developing via localhost right now.
Update - PHP fopen() line
$fullpath = $this->fileRoot . $this->fileInData['fileName'];
$file_ptr = fopen( $fullpath, 'r+' );
I should also mention I'd like to stick with Cherokee if possible. What's this deal about setting file permissions for Apache/Cherokee?
Check if the user that PHP runs under have "X" permission on every directory of the file path.
It will need it to access the file
If your file is: /path/to/test-in.txt
You should have X permission on:
/path
/path/to
and read permission on /path/to/test-in.txt
Another reason of this error may be that the directory of file does not exist.
I just add php code before fopen:
if(!file_exists(dirname($file)))
mkdir(dirname($file));
This help me out.
I am using a php script to call a backend python script.
<?php
error_reporting(-1);
$output = shell_exec("sh run.sh 2>&1");
echo "<pre>$output</pre>";
?>
The run.sh script is:
#!/bin/bash
wget http://markets.usatoday.com/custom/usatoday-com/html-mktscreener.asp
python hw7-9.py index.html
echo "done";
The output is
run.sh: wget: not found
run.sh: python: not found
done
If I run it normally from shell it works perfectly.
to try and fix the not found I did "which wget" and replace full path
/afs/cad/sw.common/bin/wget -O index.html http://markets.usatoday.com/custom/usatoday-com/html-mktscreener.asp
I get permission denied
What are the permissions of your php and your shell script?
I've used the same approach that you're using, successfully. Full ownership and attribute details below.
# ls -l
-rw-r--r-- 1 root root 2332 Jan 4 23:07 daily.php
-rwxr-xr-x 1 root root 232 Oct 30 22:43 get_stuff.sh
The user/group ownership on your system will vary. The read/write/execute permissions don't have to strictly match mine, either. But for reference, my setup is achieved via:
chmod 644 daily.php
chmod 755 get_stuff.sh
chown root:root *
