As others have mentioned, AJAX is the best solution for what you requested.
Here is a full example that does what you want. Values in a database will be updated via AJAX, with a response appearing on the page without the page refreshing.
jsFiddle (all working except AJAX)
While jsFiddle cannot demonstrate the AJAX, you can see that in action if you copy/paste the following into two files (three if you break out the javascript into its own file), and edit it to match your own database structure.
Two files are required:
One: index.php (or whatever you wish to call it)
Two: my_php_processor_file.php (if change this name, must also change in the AJAX code block in the javascript
