PHP: Simplest way to delete a folder (including its contents)

Question

The rmdir() function fails if the folder contains any files. I can loop through all of the the files in the directory with something like this:

foreach (scandir($dir) as $item) {     if ($item == '.' || $item == '..') continue;     unlink($dir.DIRECTORY_SEPARATOR.$item); } rmdir($dir); 

Is there any way to just delete it all at once?

Answer 1

rrmdir() -- recursively delete directories:

function rrmdir($dir) {    foreach(glob($dir . '/*') as $file) {      if(is_dir($file)) rrmdir($file); else unlink($file);    } rmdir($dir);  }
