Can i delete ALL files in directory ?

Question

i create a upload test using FileReference & PHP.
In this scenario user upload files to http server.
Now how can i delete all files in /files/uploads folder in AS3
AS3 Code:
req = new URLRequest();
req.url = ( stage.loaderInfo.parameters.f )? stage.loaderInfo.parameters.f : "http://www.website.com/test/upload.php";
uploadFile = new FileReference();
select_btn.addEventListener( MouseEvent.CLICK, browse );
uploadFile.addEventListener( Event.COMPLETE, complete_func );
uploadFile.addEventListener( DataEvent.UPLOAD_COMPLETE_DATA, show_message );
function browse( e:MouseEvent )
          filefilters = [new FileFilter('Images',"*.jpg;*.png;*.gif")];
          uploadFile.browse( filefilters );
function complete_func( e:Event )
          trace( 'complete !' );
function show_message(e:DataEvent)
if (e.data == 'ok')
          label_txt.text = 'The file has been uploaded.';
else if ( e.data == 'error')
          label_txt.text = 'The file could not be uploaded.';
PHP Code:
<?php
$uploads_dir = './files/uploads';
if( $_FILES['Filedata']['error'] == 0 ){
          if( move_uploaded_file( $_FILES['Filedata']['tmp_name'], $uploads_dir.$_FILES['Filedata']['name'] ) ){
                    echo 'ok';
                    exit();
echo 'error';
exit();
?>

You need call another PHP file
<?php
   $directory = './files/uploads';
   getDirectoryList ($directory);  
   //This function find all the files in the directory
   function getDirectoryList ($directory)
     // create an array to hold directory list
     $results = array();
     // create a handler for the directory
     $handler = opendir($directory);
     // open directory and walk through the filenames
     while ($file = readdir($handler)) {
       // if file isn't this directory or its parent, add it to the results
       if ($file != "." && $file != "..") {
    //$results[] = $file;
     // Delete Files
    $filename = $file;
  unlink($filename); //this delete a file
     // tidy up: close the handler
     closedir($handler);
?>
