Deep recursive array of directory structure in PHP

Answer 1

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;
}

A simple implementation without any error handling:

function dirToArray($dir) {
    $contents = array();
    # Foreach node in $dir
    foreach (scandir($dir) as $node) {
        # Skip link to current and parent folder
        if ($node == '.')  continue;
        if ($node == '..') continue;
        # Check if it's a node or a folder
        if (is_dir($dir . DIRECTORY_SEPARATOR . $node)) {
            # Add directory recursively, be sure to pass a valid path
            # to the function, not just the folder's name
            $contents[$node] = dirToArray($dir . DIRECTORY_SEPARATOR . $node);
        } else {
            # Add node, the keys will be updated automatically
            $contents[] = $node;
        }
    }
    # done
    return $contents;
}

I've had success with the PEAR File_Find package, specifically the mapTreeMultiple() method. Your code would become something like:

require_once 'File/Find.php';
$fileList = File_Find::mapTreeMultiple($dirPath);

This should return an array similar to what you're asking for.
