[Resolved] file permission

nadirah81

This is my code:

$dir = "/var/www/html/";

if (is_dir($dir))
{
if ($dh = opendir($dir))
{
while (($file = readdir($dh)) !== false)
{
$new_file = fopen("ada", "w", "666");
fwrite($new_file, 'Text');
fclose($new_file);
}
}
closedir ($dh);
}

however, I got errors stating:

Warning: fopen(ada): failed to open stream: Permission denied in /var/www/html/process_index.php on line 14 (highlighted)

I understand it is something to do with my file permission so, what i did was I gave all permission to all my directories...

chmod a=r+w+x /var/
chmod a=r+w+x /www/
chmod a=r+w+x /html/

however, when I run the script, the errors are still there.

is there anything else that I have missed out?

sorry for the technical error just now.... i've edited the post..... 😃

Shouldn't it be

$new_file = fopen("/var/www/html/ada", "w", "666");

And why do you need to read the files in $dir? And why open, write, and close the file in a loop for every file in $dir? Don't you need to do this just once like

$new_file = fopen("/var/www/html/ada", "w", "666");
fwrite($new_file, 'Text');
fclose($new_file);

FYI, trying to fopen the ada file is for testing purposes. After this, my aim is actually to create a new folder, and in the folder files are created using loops ( 1, 2, 3, 4, etc) and write to it.

However, I've tried putting it as:

$new_file = fopen("/var/www/html/ada", "w", "666");

but, i still get the same error.

I've also tried deleting the loops and only uses

$new_file = fopen("/var/www/html/ada", "w", "666");
fwrite($new_file, 'Text');
fclose($new_file);

but, as usual, the errors are still there..... have anyone has any idea what is wrong?

Make sure the directory where you wish to create the file has the correct permissions i.e. Chmod the directory 777 so you can write to it.

nadirah81

I've done that already but still not working..... 🙁

This is probably not the problem, but you should get rid of that 3rd parameter you're passing fopen.

// wrong
$new_file = fopen("/var/www/html/ada", "w", "666");

// right
$new_file = fopen("/var/www/html/ada", "w");

From the manual:

The optional third use_include_path parameter can be set to '1' or TRUE if you want to search for the file in the include_path, too.

Welcome to my world, lol ... My Thread on the Problem

You wouldn't happen to be running Fedora as your OS would you?

Is there some apache config or php.ini file setting that must be turned 'on' before file writing is allowed?

MikeSnead

If you find you cannot open a file even with 777 permissions... check your SELinux settings...

nadirah81

yes... u r rite. I'm running my php on Fedora Core 3.

Which setting should I check? How do I go to my SElinux setting... sorry, I really have not change anything in the SElinux setting. Which part in the setting should I change?

Thanks for telling about that. I really have no idea.

MikeSnead

Go to... Applications > System Settings > Security Level

Enter your root password at the query prompt that pops up and you'll enter the nifty little Security Config Menu.

Click on the SELinux tab and look in the white box at the bottom. Expand the 'Transition" options and you should get a list of check boxes. Check the one that says "Disable Selinux Protection for httpd daemon".

Restart your webserver (reboot or do "service httpd restart" at a root command prompt) and things should be good to go (assuming your permissions are in check otherwise).

Thanks MikeSnead. I've resolve my problem. Thanks to your help again. Yes, after I've disable the SELinux security, my fopen works fine.
