php & ajax

ello all, Im a beginner at php. but I was able to get this script to work. Now I am looking to have it automatically refresh itself using ajax every 10 seconds. Can somebody explain or show me how to do this. Thank you. PHP Code: | | |<?php $httpfile = file_get_contents('http://www.game-monitor.com/client/buddyList.php?uid=8654&listid=0&xml=1'); $doc = DOMDocument::loadXML($httpfile); $myBuddyNodes = $doc->getElementsByTagName('buddy'); /////not neccessary, but im using it $nameStatusDoc = new DOMDocument('1.0', 'iso-8859-1'); $rootElement = $nameStatusDoc->createElement('PetesList'); $rootElement = $nameStatusDoc->appendChild($rootElement); ///////// echo "<table border = '0' cellpadding= '2' bgcolor='#616042'>\n<thead><tr><th></th><th></th><tr></thead>\n"; foreach ($myBuddyNodes as $node) { echo "<tr>"; echo "<td><font size='-1'>".$node->firstChild->nextSibling->nodeValue."</font></td>"; if($node->firstChild->nextSibling->nextSibling->nextSibling->nodeValue == "Online") |
