Send a string to another web site

On my "receiver" web site, I get the customer's information from a form and assemble this information as a string.

Now I want to send this string to a separate "listener" web site.

(Later, the "listener" site will store the string somewhere.)

I can't spot how to do this. I think it involves headers somehow.

Could someone point me in the right direction, please ?

I typically use cURL: www.php.net/curl

This all depends on how the listener site is set up. Does it host a form? Does it have an API? Do you share a database with it?

You could have your form submit directly to the listener site by setting the ACTION attribute of your form to point there.

You could have your form submit to your own site and have your own script create a curl request as NogDog suggested.
