recursive directory listing, plus ul/li output

 / Published in: PHP
 

This will accept a directory reference, and take a recursive listing of files and directories. The 2nd function will then create a structured ul/li list of the results. The functions can be used in combination as illustrated, or with just the recursive directory lister alone.

How could I make the listing output link to the file/dir?

Posted By: MMDeveloper on February 9, 2009

quickest way would be to just modify the readDirR function as follows

function readDirR($dir = "./") { $listing = opendir($dir); $return = array (); while(($entry = readdir($listing)) !== false) { if ($entry != "." && $entry != "..") { $dir = pregreplace("/^(.*)(\/)+$/", "$1", $dir); $item = $dir . "/" . $entry; if (isfile($item)) { $return[] = '<a href="'>' . $entry . ''; } elseif (is_dir($item)) { $return['<a href="'>' . $entry . ''] = readDirR($item); } else {} } else {} }

return $return;

}
