curl in php

i inserted a domain of different server say, www.someotherdomain.com in my domain(www.mydomain.com) using frames. now i need to login and get into a form of www.someotherdomain.com. how to send username and password to another domain of different server from my domain? can v do this using curl in php?

note: login should be done automatically, that is on server side. so that the customer may not know they logged in. the view should be like this: they have to click a link of my site and get a form of another site.

but before entering into the form of another domain, i need to login. how to overcome this. please help me.

thanks for understanding.

 

It can easily be achieved by using curl_cookies, and curl_post

 

can u give me some examples. because i tried. but i dont know to submit the login page automatically also i dont think the username and password are posted to that domain. i am very much confused. pls, help me with the coding.

thanks
