Hi
Im trying to chmod a directory to 777 using chmod("folder", 0777); but it gives the error
Code: Select all
Warning: chmod(): Operation not permitted in /xxx/xxx.php on line nn
Actually I want to write data to a file - if the file does not exist then create it. This file may be deleted manually many times. So I cannot chmod it to 777 manually.
I cant use chmod($ilename,0777) because the filename may not exist.
Any idea how to get this done ?
Thanks

How about checking wheter file exists before that using file_exists();?
I guess PHP or Apache running user (www or nobody in most cases) doesn't have permission to write on parent of "folder" directory. You would have to chmod chown the parent directory.

If it doesnt how would I create the file ? For that I would need to do chmod(0777) to that file which doesnt exist !

Code: Select all
if (!file_exists("/example/file.dat")) {
fopen('/example/file.dat', 'w');
}

I think anjanesh is pointing out PHP doesn't have permission to write to that directory.
So, as I said, anjanesh needs to make the parent directory writable to Apache user.
