puzzler - auto directory listings

[jpmoriarty]

Hey all - still a newbie, real odd one here.

I've written the following function:

  function dir_contents($directory)
  {
    $handle = opendir ($directory);
    $file = readdir($handle);
    $file = readdir($handle);
    while ($file = readdir($handle))
    {
//      if (substr($file,0,1) == "-")
//      {
	echo "<p>Is <b>'".$file."'</b> a directory? ".is_dir($file)."</p>";
        if (is_dir($file) == 1 )
        {
          echo "<p><b>Directory:".$file."</b><i>".$directory."</i></p>\n";
          dir_contents($file);
        }
	else
        {
          echo "<p>".$file."</p>\n";
        }
//      }
    }
    closedir($handle);
  }

which is supposed to do a directory listing. the idea is that it checks if the file its looking at is a directory, and if it is then it goes into that and lists the files in there too.

Firstly, when i ran it in one of my directories it worked nicely, except that it didnt go any further in than one level - it thought that the sub sub directories were files. so then i fed it the sub directory to start with , and it still thinks that the directory is a file! If i do a is_dir() for the directory at the end of the document then it does return a value of 1, so it knows really that it is a directory, but wont run the script on it!

Is there something wrong with what i've done above? you can see various lines I've put in and then taken out to try to get it to work, but I cant figure it out.

Many thanks in advance

did originally state that i'd found others and therefore you could ignore this, but i now cant understand the others and cant understand why this wont work - so i'm open to suggestions again!

sorry, just trying to keep this one alive!! Noone any ideas why it doesnt work?

I think this is what you are trying to do:

function check_dir($dir) {
   $dir = opendir("/path/to/dir")
   while (false != ($file = readdir($dir))) {
      if ($file == "." || $file == "..") continue;
      if (is_dir($file)) {
         check_dir($dir . "/" .  $file);
      } else {
         print $file;
      }
   }
}

Hiya I have just joined and very much a newbie.
I tried to used the check_dir function changing the final print statement to display file_name links in an html page and got stuck in a fatal loop. How can I actually drill down on directories to see just the files in it?

I tried using is_dir too and can identify the files just cant seem to write the code to display the files in my html page.

Any tips or suggestions or tutorials where I could learn more about traversing a directory would be great

Thanks
Bobby
