Is there a way to call a php function from a button press to display
the results further down on the same page? I want to avoid setting up
an 'output-area' in a frame or having to put my function in a separate
script.

As deployment of XML data and web services becomes more widespread, you may occasionally find it convenient to connect an HTML presentation directly to XML data for interim updates without reloading the page. Thanks to the little-known XMLHttpRequest object, an increasing range of web clients can retrieve and submit XML data directly, all in the background. To convert retrieved XML data into renderable HTML content, rely on the client-side Document Object Model (DOM) to read the XML document node tree and compose HTML elements that the user sees.
