Cant set correct file permissions chmod()

robembra

Hi,

I have a script that reads through a dir and checks the file permissions agaist a list, but i cant seem to set the permissions correctly. I am using the code below:

$perms = substr(sprintf('%o', fileperms($file)), -4);chmod($new_folder_path, $perms);

Say a file is 0755 it will make it 431 or something and then I cant read the dir at all. I have tried all sorts playing with the format of the variable but im just going backwards.

$perms = 0755 and is numeric

I thinks its something to do with octdel but I dont understand them .

Thanks

A note on [man]chmod[/man] is probably your problem ...

Note: The current user is the user under which PHP runs. It is probably not the same user you use for normal shell or FTP access. The mode can be changed only by user who owns the file on most systems.

I have sorted the problem it was that chmod wasn't accepting 0755 stored in $perms so used this instead:

$perms = fileperms($file);
chmod($new_folder_path, $perms);

$perms now = 16877 works for 0755.

Jusr dont understand why it wont accept 0755 stored in a $var but will accpet 16877,
