Post variable to php page from Flash

I am trying to set up a form in a flash movie that will post the users entry to a php page. I then need the php page to re-direct the user to a page to show a result.

I have the following AS in the flash form. It seems to post to the php page but from within the flash movie. Rather than taking them to the php page, as a non-flash form post would.

on (release) {
loadVariablesNum(“search.php”, 0, “POST”);
}

Is there a way I can get the flash form to post to the php page in the same way a non-flash form would post.

Hope this makes sense! Basically, when the user clicks the submit button, I need the browser to load another php page that gets the user’s input via post.
