Chmod 666 and access denied for getimagesize

Question

First of all, this is not a duplicate of : Permission denied on getimagesize

I got following code, where I sat an chmod for the image, and then I wan't to get it's size.

@chmod($path."/".$filename, '0666');
getimagesize($path . "/" . $filename);

But if I set a chmod, I'm receiving this error message:

failed to open stream: Permission denied in[...]

What is the problem? All files and the directory has the same group and owner - www-data.

Answer 1

Actually do you really need to chmod before getimagesize?

if so, maybe u can try putting umask before chmod. something like this?

$old = umask(0); 
chmod($path,0777);
umask($old);

Answer 2

Try putting a / before path. Not sure about php, but I know python wont add the initial / to certain path operations, so it may be looking for a relative path instad of absolute:

@chmod("/". $path."/".$filename, '0666');
getimagesize("/". $path . "/" . $filename);

Answer 3

First of all, chmod won't succeed (permission will be denied; maybe the error you get is from chmod?) if www-data (assuming that's the user of your webserver) doesn't have write access to the directory $path. Ensure www-data has read-permission to all parent dirs of $path and write-permission to $path.

Also, ensure that you use absolute paths, both in chmod and getimagesize.
