Deep recursive array of directory structure in PHP

by

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;
}
