437000 twitter oauth automatic allow to access a application.

for example, there is a site when click "sign in with twitter", it will go to a page, there, you will need input username and password, then click, then will show a page, there are 2 buttons, "Deny","Allow". I need a script which will automaticlly input username and password, and accept "Allow". so what i need is a php script, i can run at command line, just one click then the user has automatic accept the site.
