Question

I’m trying to put some folders on my hard-drive into an array.

For instance, vacation pictures.
Let’s say we have this structure:

• Set 1
  • Item 1 of Set 1
  • Item 2 of Set 1
  • Item … of Set 1
• Set 2
  • Subset 1 of Set 2
    • Item 1 of Subset 1 of Set 2
    • Item … of Subset 1 of Set 2
  • Subset 2 of Set 2
  • Random file, not a dir.
• Set 3
• …

I want to have something like that, as an array.
Meaning I have 1 big array and in that array are more arrays. Each set and subset gets its own array.

I’m trying to make it look something like this:

Array
(
    [Set 1] => Array([0] => Item 1 of Set 1, [1] => Item 1 of Set 1,...)
    [Set 2] => Array([Subnet 1] => Array([0] => Item 1 of Subset 1 of Set 2,[1] => ...), [Subnet 2] => Array([0] => ..., ..., ...), ..., [0] => Random File)
    [set 3] => Array(...)
    ...
)

I came across this: http://www.the-art-of-web.com/php/dirlist/

But that’s not what I’m looking for. I’ve been meddling with it but it’s giving me nothing but trouble.

Here’s an example, view source for larger resolution(no clicking apparently…).

I recommend using DirectoryIterator to build your array

Here’s a snippet I threw together real quick, but I don’t have an environment to test it in currently so be prepared to debug it.

$fileData = fillArrayWithFileNodes( new DirectoryIterator( '/path/to/root/' ) );

function fillArrayWithFileNodes( DirectoryIterator $dir )
{
  $data = array();
  foreach ( $dir as $node )
  {
    if ( $node->isDir() && !$node->isDot() )
    {
      $data[$node->getFilename()] = fillArrayWithFileNodes( new DirectoryIterator( $node->getPathname() ) );
    }
    else if ( $node->isFile() )
    {
      $data[] = $node->getFilename();
    }
  }
  return $data;
}
