[Resolved] Creating directory questions.

Napster

I have been reading about the functions that will allow me to make directories. I have found the function mkdir which will make a directory but I am trying to find out what is the mode integer to use so that it gives read write and execute abilities to the owner and everybody else.

Also, how do I check if the directory already exsists?

Thank you in advance.

if (!file_exists($dirname)) {
   if (@mkdir($dirname, 0777)) {
      // success
   }
   else {
      // failure
   }
}
else {
   // file or directory with that name already exists
}

as for "0777" mode, the first digit will almost always be 0 (atleast for what you'll be doing) and the next three digits are for owner, owner's group, and everybody else's privileges (respectively)

7 = read + write + execute

the breakdown:
0 = no privileges
1 = execute privileges
2 = write privileges
4 = read privileges

Just add them up to what you want (1 + 2 + 4 = 7)

so access privileges of 5 = 1 + 4 = execute and read privileges, but no write privileges

So using this code...

<?php

  $filename = '/josh';

  if (!file_exists($filename)) {

if (@mkdir($filename, 0777)) {

  echo "created the directory $filename";

}
else {

  echo "couldn't create the directory.";

}
  }
  else {

echo "directory already exsists.";

  } 


?>

I open up the file on my server and the first time it says, "created the directory /josh" then I refresh and it says, "directory already exsists". So I go to the http://localhost I do not see the folder /josh. I then go to http://localhost/josh and that gives me a 404 error page. Why is that, and is it supposed to be happening. Also, how do I get the folder /josh to show up. The script with that php code still says that the direcory already exsists.

I wouldn't think PHP would have the authority to add a new directory to the root directory of the server and if it somehow managed to create "/josh" in the root-directory (where "/root" and "/tmp" is hung off of) then you need to secure that machine ASAP!! Of course I am assuming that you are not running Windows.

That's probably not the case and I would think it'd create it in the webroot directory, and you'd think http://localhost/josh would work. Try adding "./josh" instead of "/josh" and see if it works.

If it does, then it did in-fact add "/josh" somewhere else.

If you are running linux/bsd/unix then as root type:

find / -name josh

that will track down all directories named josh on your filesystem

I am using my own windows XP server just for my personal use. Anyways I tried ./josh and it worked perfectly. Thank you so much.
