Reading dir from array

Question

i'm using a dropbox api, and this is a part of my script:

$folders = $dropbox->GetMetadata("");

echo '<pre>';
print_r($folders).'
echo </pre>';

It returns an array like this:

stdClass Object
(
    [hash] => 9539e595b82fce68ee1bcda37a23848f
    [thumb_exists] => 
    [bytes] => 0
    [path] => /
    [is_dir] => 1
    [icon] => folder
    [root] => dropbox
    [contents] => Array
    (
        [0] => stdClass Object
            (
                [bytes] => 0
                [rev] => e8b1169b0b4
                [revision] => 3723
                [icon] => folder_camera
                [path] => /Camera Uploads
                [is_dir] => 1
                [thumb_exists] => 
                [root] => dropbox
                [modified] => Sun, 04 Jan 2015 08:12:03 +0000
                [size] => 0 bytes
            )

        [1] => stdClass Object
            (
                [rev] => e5a1169b0b4
                [thumb_exists] => 1
                [path] => /DSC_0346.JPG
                [is_dir] => 
                [client_mtime] => Sun, 14 Dec 2014 08:52:25 +0000
                [icon] => page_white_picture
                [bytes] => 1777550
                [modified] => Sun, 14 Dec 2014 08:52:25 +0000
                [size] => 1.7 MB
                [root] => dropbox
                [mime_type] => image/jpeg
                [revision] => 3674
            )

But i just cant figure out how i list only all the directory names in one list. The directory names are named [path] in the array.

Can someone explain it to me?

use the complete form of foreach($array as $key => $value) then compare $key === "path" — Félix Adriyel Gagnon-Grenier

The question is not 100% clear.

So if you want to list folders only do this:

$folders = $dropbox->GetMetadata("");

echo '<pre>';
foreach($folders->contents as $item) {
  if ($item->is_dir==1) {
    echo $item->path.'<br />';
  }
}

echo '</pre>';

hope my guess is what you are asking for

You need to loop over the contents property of your object as that is the array containing the folder objects where the path and is_dir properties are stored:

foreach ($folders->contents as $obj)
{
  if ($obj->is_dir === 1)
  {
    echo $obj->path;
  }
}

Not all folder contents are directories. You would need to check for the is_dir flag within the contents array

Try this:

$paths[]  = $folders->path ; //return the root path(/)

foreach($folders->contents as $pathObj)
{
   if ($pathObj->is_dir==1) {   

       $paths[]  = $pathObj->path ;
   }
}

print_r($paths);
