Upload a file using PHP and Jquery without displaying the browse window?

I 开发者_如何学编程want to upload a file using PHP and Jquery.I know the path where it is saved(Path is static with the same file name).

Every time when the user click the upload button then I need to upload the file in the backend and displaying only the uploading gif image in the front end.So is it possible to make the upload without displaying the browse window using Jquery and PHP?

for that u can use jQuery Uploadify: http://www.uploadify.com/demo/
