Hello!

the code below echoes "error". What am I doing wrong?

PHP Code:

mkdir("copy", 0777);
$ret_val = copy("test.txt", "copy");
echo ( $ret_val ? "success" : "error" ); 


Also tried this and it's the same:

PHP Code:

mkdir("copy", 0777);
$ret_val = copy("test.txt", "copy/test.txt");
echo ( $ret_val ? "success" : "error" ); 


But if I want to make a copy of test.txt in the same directory, this goes fine.

Is there any function to move a file in another directory?
Thanks

PHP Code:

mkdir("copy", 0777);
$ret_val = copy("test.txt", ".copy/test.txt");
echo ( $ret_val ? "success" : "error" ); 


Try that code. I added a period in front of the subfolder 'copy'. PHP needs to have that period there.

PHP Code:

mkdir("copy", 0777);
if(file_exists("test.txt") && @chmod("test.txt", 0777) && is_writable("copy/")){
$ret_val = @copy("test.txt", "copy/test.txt");
echo ( $ret_val ? "success" : "error" );  
} 


You may want to put from check in there, and try chmodding it. also using '@' will tell PHP weather it worked or not.

Also, is any error code coming up? it could be that your not making copy/ directory writable. Another thing, you may need to make the file local to the server, for example '/home/files/copy/'

coolkbk585's advise also echoes "error", rogem002's code didn't echo anything. I also tried with the whole path to the new file (including the home or root folder).

I tried to create the folder by my self with the FTP client and set the permition to 777. Then I got success and the file was copied succesfully.

Interesting is that if I set the folder permition while creating the directory; mkdir("copy", 0777) - the permition actually isn't 777 but 755. So I tried to separate this process and executed:

PHP Code:

mkdir("copy");
chmod("copy", 0777);
$ret_val = copy("test.txt", "copy/test.txt");
echo ( $ret_val ? "success" : "error" ); 


Permition actually was 777 but I still got the error and the file wasn't copied .

Per FTP client created folder, the argument "user" in properties has value 6267 but programicaly created folder has 99 in the "user" argument. Maybe this could be the reason?

You may first need to allow permissions in the parent directory you are running the script from to allow php to create and write to the directory.

Try:

PHP Code:

mkdir("copy", 0777);
if(file_exists("test.txt") && @chmod("test.txt", 0777) && is_writable("copy/")){
$ret_val = @copy("test.txt", "copy/test.txt");
echo ( $ret_val ? "success" : "error" );  
} else {
echo "error is either: file does not exist. the file/folder is not writable.";
} 


The permission of the parent directory is set to 777 (the directory in which is the script). Also the parent directory was created per FTP client so the user is 6267.

rogem002's code echoes this:"error is either: file does not exist. the file/folder is not writable." and the created folder "copy" has permission set to 755.

Thanks for helping me guys!

Sorry to butt in here, but i just want to ask something, why is it on the thousands of PHP install scripts out there why do they always ask you to manually cmodd files/folders to writable why dont the script automatically cmodd it to the correct permission and even cmodd it back at the end is there any real reason?

I would like to know if there is a reason not to, as i am writible my own install scripts and stuff.

Thanks,
sorry to butt in again

Some servers are configged so that the mkdir function can not create a directory with permissions greater than 644 or whatever value is set by sysadmin.

The soultion is to mkdir $newdir; and then on the next line
chmod $newdir 777;

and then continue your script.

You don't need 777 on a directory if you are going to put files there by your script and then read them by apache. 755 will be quite enough in this case.

This happens because usually user who uploads the script and user who runs apache (I mean user ID in linux system on the server) are different and thus the php script which is started from apache simply cannot write to folder which is owned by another user. Also usually apache user does not belong to the same group as script owner, that's why setting group write permission also does not give effect. Thus the only way to write to folder from the script is setting directory world writable. But considering security reasons it is not recommended to leave directory world writable, especially if nobody is expected to write there.

If a system is configured in such a way that all users are in same group with apache user and newly created dirs permissions are 775 then you will not have to chmod the dir manually to write there from the script, but you will have to chmod it AFTER to prevent other users' scripts to write here. So in general case there is no way to avoid manual chmodding at all.

Well, it is, but only if you are not going to write to the filesystem from the script at all.

Per FTP client created folder, the argument "user" in properties has value 6267 but programicaly created folder has 99 in the "user" argument. Maybe this could be the reason?

I missed this post the first time through. Sorry I repeated what you said you already tried.

Yes I think it can. I don't know enough of the detail to be specific. You may want to investigate the change owner function (chown, I think). It may hold the key to what you are trying to do.

No problem colbyt.

chown() also didn't solve my problem. Only the superuser can use it.

I mailed the server administrator and got the explanation that a folder created per a php scipt has nouser/nogroup privilegion and that's why writing isn't possible in such a directory. That's because the safe-mode is turned on (on the server) and I should get more information on this link: http://si2.php.net/manual/en/features.safe-mode.php.

Well ... I'll find more information about how to write into a php script created folder while safe-mode is turned on. But if someone could give me any advices from the first hand about this, I'll appritiate it.

Thanks to all!
