you can use post or get request to your current page (or to another page) using <form> tag or ajax. Then in the php you will use $_REQUEST (or $_POST or $_GET) which act as associative array with the key being the name of your variable. So if you submitted mypage.php?foo=bar

in php $_REQUEST['foo'] will be bar.
