PHP Script to save text box content and generate random file name?

I think the title pretty much explains it.

Is there a PHP script out there that will let me create a .txt file with a random filename, then save the data from a text box form to it?

I have a slight feeling I may be asking for too much.

But if you can help, that'd be great.

Thanks.

file_put_contents('writabledir/' . md5(time() + mt_rand()) . '.txt', $_POST['text']);

PHP:

 

This indeed is a very good solution premium!. But I wonder why you need to do this. And you still have the rare event of file name collision.
