set permissions for all files and folders recursively

Why don't use find tool for this?

exec ("find /path/to/folder -type d -exec chmod 0750 {} +");exec ("find /path/to/folder -type f -exec chmod 0644 {} +");

My solution will change all files and folder recursively to 0777. I use DirecotryIterator, it's much cleaner instead of opendir and while loop.

function chmod_r($path) {    $dir = new DirectoryIterator($path);    foreach ($dir as $item) {        chmod($item->getPathname(), 0777);        if ($item->isDir() && !$item->isDot()) {            chmod_r($item->getPathname());        }    }}

This is tested and works like a charm:

<?  header('Content-Type: text/plain');  /**  * Changes permissions on files and directories within $dir and dives recursively  * into found subdirectories.  */  function chmod_r($dir, $dirPermissions, $filePermissions) {      $dp = opendir($dir);       while($file = readdir($dp)) {         if (($file == ".") || ($file == ".."))            continue;        $fullPath = $dir."/".$file;         if(is_dir($fullPath)) {            echo('DIR:' . $fullPath . "\n");            chmod($fullPath, $dirPermissions);            chmod_r($fullPath, $dirPermissions, $filePermissions);         } else {            echo('FILE:' . $fullPath . "\n");            chmod($fullPath, $filePermissions);         }       }     closedir($dp);  }  chmod_r(dirname(__FILE__), 0755, 0755);?>
