fopen throws Permission Denied error

I am using Drupal(php based open source software) to build a website.

Right now I am experiencing a weird problem. When I use fopen in a test.php and run from command line: "php test.php", I can open file and read/write/append, but if I include that portion of code in side the drupal module I wrote, I get permission denied error.

Can anyone help me on this? Many thanks

 

I re-evalued my problem, i don't think it has anything to do with drupal any more

the problem now is that I can read a file but not write and append.

here is the permission of the file I want to open:

-rwxrwxrwx 1 root root .... pass.txt

 

Maybe show us the fopen code?

 

here is the code:

$file = "/web/website/test.txt";
$fh = fopen($file, "r");

$data = fgets($fh);

print $data.

now the problem is if I put the text file under /tmp, I can read and append,

but if I move to another directory, I can't read, write, append. all throw me permission denied error.

I checked the directory permission, it's 777, and the user and usergroup are apache apache.

 

The problem is you do not use the / from the beginning alone. That indicates that you are using the absolute root. Which is outside of the web folder. Of course it is going to throw an error... use ./ instead of / at the start.

 

I tried changing / to ./, I got this error

warning: fopen(./web/files/test.txt) [function.fopen]: failed to open stream: No such file or directory

 

try

$file = "web/website/test.txt";

PHP:

 

I still get No such file or directory error

 

I changed the file name from test.txt to test,

now I can read the file, but still can't write or append to the file.

 

Ok seems like you are defining the directory wrong. If the file is 1 level deeper use ../ if it's 2 levels ../../

 

It's your file structure. You need the full path to your server home directory.

For example on my hosting (MediaTemple) I would have to address the file in this way to open it for my domain ProbablySucks.com

/domains/probablysucks.com/html/test.txt

I suggest FTP'ing to your directory with FileZilla and copying the server path from the top it shows you.

 

jj0914, did you solve your problem? I have the same problem here:

fopen("/opt/www-data/test.log", "a");

gives Permission Denied. I checked the permissions on the filesystem, apache is the owner (if not, still everybody has write permission). The path is correct.

getmyui() and getmygid() give 48 and 48. stat('/opt/www-data/test.log')['uid'|'gid'] same values. I tried using /tmp instead, works. I cannot see why I can't write to /opt.

Also tried using system("touch /opt/www-data/test") which gives the same issue. On the console with sudo -u apache touch /opt/www-data/test it works.

Any idea? (As always: works on another system but can't see the difference.)

Thanks,
