PHP - Readdir / Scandir - Formats Of Filenames?

Hi all

I am using this function to list all files and folders within a directory

Code: [Select]
function getFilesFromDir($dir) {

  $files = array();
  if ($handle = opendir($dir)) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            if(is_dir($dir.'/'.$file)) {
                $dir2 = $dir.'/'.$file;
                $files[] = getFilesFromDir($dir2);
            }
            else {
              $files[] = $dir.'/'.$file;
            }
        }
    }
    closedir($handle);
  }

  return array_flat($files);
}

function array_flat($array) {

  foreach($array as $a) {
    if(is_array($a)) {
      $tmp = array_merge($tmp, array_flat($a));
    }
    else {
      $tmp[] = $a;
    }
  }

  return $tmp;
}

When I call the function I give the dir as a variable, however if the dir I want is a sub-dir of a current dir then the list starts from the main dir

Basically say my file test.html is contained here files/test/test.html, the input I need to give is files/test/. This would then output in the array ->files/test/test.html. What I would like the output to be is test/test.html. How do I edit my recursive function to start from the final folder in the input?

Thanks

Hi all.

I'm trying to build a dynamic multiple tiered navigation menu that operates on the existence of directories.  So far, I have some code that will read through the document root, and one sub level of directories but I'm not sure how to get into the third level of directories.  Here's what I have so far...

The code:

      $docroot=scandir($_SERVER['DOCUMENT_ROOT']);

      unset($docroot[array_search('.',$docroot)]);

      unset($docroot[array_search('..',$docroot)]);

      unset($docroot[array_search('php',$docroot)]);

      unset($docroot[array_search('css',$docroot)]);

      unset($docroot[array_search('input_forms',$docroot)]);

      $docroot=array_values($docroot);

      

      //Build tier 1

      echo "<div class=\"tier\">";

      echo "<a href=\"/index.php\">Home</a>";

      foreach($docroot as $value1){

         if(is_dir($value1)){

            $t2=scandir($_SERVER['DOCUMENT_ROOT'] . "/" . $value1);

            unset($t2[array_search('.',$t2)]);

            unset($t2[array_search('..',$t2)]);

            $t2=array_values($t2);

            $t1[]=$t2;

            

            echo "<a href=\"/$value1/\">";

            $value1=str_replace("_"," ",$value1);

            $value1=ucwords($value1);

            echo $value1;

            echo "</a>";

         }

      }

      echo "</div>";


The output:
Code: [Select]
[it automatically builds the first tier of the menu with some stylesheet definitions and places it here.  I did this just for testing purposes.]

Sorry for the noobie question, I am just a beginner still. I am trying to use the readdir function to echo back all the contents of a folder. The directory that I want to read back has 31 empty folders. I am able to get them to read back, but they are in a random order and there are two additional files at the top named "." and ".." -- any idea how to fix these? Here is my code and pictures:

Quote

$path = "c:/test/";
if(is_dir($path)) {
   if($dir_handle = opendir($path)) {
      while($filename = readdir($dir_handle)) {
         echo "filename: {$filename}<br>";
            }
               closedir($dir_handle);
         }
      }

Hi folks,

First time posting here and a bit of a novice at PHP, but am learning....

I am fiddling with a small bit of code to create a very basic php gallery (I'm sure everyone has at some point). I started off with a mysql intergrated one then thought I would try a new one without the mysql.

Its working fine but I am just having one very strange problem.

Basically, I started of with just /mygallery/index.php?w=... where ... = the location (physical folder) of photos. I use opendir to open the contents of w= and parse whether it is a directory or a file (then narrow it down to just images).

If it is a dir, then I present it as a link to that folder (sub-album) if it is a photo, I present a thumb link to the image.

Now I have added a mod_rewrite rule to allow my urls to be of the form 'mygallery/album/subalbum'   this gets ocnverted into 'mygallery/index.php?w=album/subalbum'

Now the funny bit. If I create a new folder in one of the subalbum, e.g. : mygallery/album/subalbum/<b>New Folder</b> the code works. i.e. when I point my browser at 'mygallery/album/subalbum' I get a link showing 'New Folder'

But if I create a new folder of any other NAME it does not appear in the list!! So if I just rename 'New Folder' to 'New Folde' it drops of the web page!!!

Now I am really not sure what the hell is going on...

Hope someone can help.

I will post my code if necessary.

Thanks in advance!

Hey guys basically with a simple script that I made I need some help with it's doing my head in.

What i'm trying to do is allow multiple filetypes to be shown by readdir, i want both .zip and .rar to be in the list, not just .zip how would i add .rar in this method as well to be visible on readdir?

<?php
$dirname = "/home/test/";
$dir = opendir($dirname);
$extension = array_pop(explode(".", $file));

?>

<?php
while(false != ($file = readdir($dir)))
{
 if ($file != "." && $file != ".." && array_pop(explode(".", $file)) == "zip") {
echo("





<b>&raquo; <a href='$dirname$file'>$file - Download</a> <br />     </b>



");
}
}

?>
