Spaces to display levels in dir structure list ?

[Peuplarchie]

Good day to you all,

        working on listing a directory the way I want, I'm trying that for each level of file there is a number of spaces in front of the file and/or folder of that level. EX :

Folder 1
--Folder 2
--Image 1
--Image 2
--Image 3
Image 1
Image 2

How can I add that spacing on each level ?

Here is my code :

<?php

$directory = "Art/";
function dirList ($directory)
{

//create 2 arrays - one for folders and one for files
   $folders = array();
   $files = array();

// create a handler for the directory
$handler = opendir($directory);

// keep going until all files in directory have been read
while (false !== ($file = readdir($handler))) {  

    // if $file isn't this directory or its parent,
    // add it to the results array
    if ($file != '.' && $file != '..')

    // If file is directory, mark it in bold.
   if(is_dir($directory.$file)) { 
    array_push($folders,$file);

    // Else not styled
    }else{
    array_push($files,$file);

}
}


// tidy up: close the handler
closedir($handler);

foreach($folders as $folder) {
  echo "<strong>".$folder."</strong>  <a href=\"javascript:show('".$folder."');\">Show</a>- <a href=\"javascript:hide('".$folder."');\">Hide</a><br />";

echo "<div id=\"".$folder."\">";
dirList($directory.$folder.'/');

echo "<br/><br/></div>";


}

foreach($files as $file) {
  echo $file."<br />";
}


}

dirList($directory);

?>

Thanks !

You're ignoring the current/parent dir, but you actually need to use them. This looks to me like a job for some multi-dimensional arrays, or perhaps just one. You'd have to track how deep and high the array gets using counters, but lets say you have a folder 'A' with 3 sub-folders 'A1', 'A2', and 'A3', and there are 3 files in each folder. You want to build an array that looks like this:

$listing['A'] =>
  ($folder['A1'] => ("file1", "file2", "file3"),
  $folder['A2'] => ("file4", "file5", "file6"),
  $folder['A3'] => ("file7", "file8", "file9"))

Of course, your listing array will probably go deeper and wider than that, but hopefully you get the picture. The height and depth counters will help you access the array elements later, so use those as you build your code.

I'm also envisioning some functions here. Something like:

if($file == '.')
  {
  $depth = setCurrent($file);
  continue;
  }
if($file == '..') 
  {
  setParent($file);
  continue;
  }
if(isdir($file))
  $height = setFolder($file);
else
  $height = setFile($file);

Hopefully this will point you in the right direction. Obviously, there's more code involved here, but I'll leave that to you or anyone who has time to think it all out.
