Deep recursive array of directory structure in PHP

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
  • Ite

Answer 1

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;
}
