PHP recursive delete function

Question

I wrote recursive PHP function for folder deletion. I wonder, how do I modify this function to delete all files and folders in webhosting, excluding given array of files and

Answer 1

1. You could provide an extra array parameter $exclusions to recursive_remove_directory(), but you'll have to pass this parameter every time recursively.

2. Make $exclusions global. This way it can be accessed in every level of recursion.

Answer 2

Try something like this:

$it = new RecursiveIteratorIterator(
  new RecursiveDirectoryIterator('%yourBaseDir%'),
  RecursiveIteratorIterator::CHILD_FIRST
);

$excludeDirsNames = array();
$excludeFileNames = array('.htaccess');

foreach($it as $entry) {
  if ($entry->isDir()) {
    if (!in_array($entry->getBasename(), $excludeDirsNames)) {
      try {
        rmdir($entry->getPathname());
      }
      catch (Exception $ex) {
        // dir not empty
      }
    }
  }
  elseif (!in_array($entry->getFileName(), $excludeFileNames)) {
    unlink($entry->getPathname());
  }
}

I'm using this function to delete the folder with all files and subfolders:

function removedir($dir) {
    if (substr($dir, strlen($dir) - 1, 1) != '/')
        $dir .= '/';
    if ($handle = opendir($dir)) {
        while ($obj = readdir($handle)) {
            if ($obj != '.' && $obj != '..') {
                if (is_dir($dir . $obj)) {
                    if (!removedir($dir . $obj))
                        return false;
                }
                else if (is_file($dir . $obj)) {
                    if (!unlink($dir . $obj))
                        return false;
                }
            }
        }
        closedir($handle);
        if (!@rmdir($dir))
            return false;
        return true;
    }
    return false;
}

$folder_to_delete = "folder"; // folder to be deleted

echo removedir($folder_to_delete) ? 'done' : 'not done';

Iirc I got this from php.net
