How to retrieve Twitter search results dynamically using Ajax? - php

Question

I'm building a Twitter application which depends on retrieving Twitter search results. It works fine but I still need to update the page to get the new tweets.
How to let the page refreshes itself dynamically just like Twitter Widgets, to show the new tweets ?
Here is my code, please show me how, because I tired many scripts and it doesn't work with me.
Twitter Class
<?php
class Twitter
{
public function __construct(){ }
public function searchResults( $search = null )
{
$url = "http://search.twitter.com/search.atom?q=" . urlencode( $search ) . "&lang=en&rpp=50";
$curl = curl_init();
curl_setopt( $curl, CURLOPT_URL, $url );
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, 1 );
$result = curl_exec( $curl );
curl_close( $curl );
$return = new SimpleXMLElement( $result );
return $return;
}
}
?>
Test Class
<?php
require_once("twitter.class.php");
$Twitter = new Twitter;
$results = $Twitter->searchResults("usa");
foreach( $results->entry as $result )
{
echo "<h3><a href=\"". $result->author->uri ."\">". $result->author->name ."<a/></h3><img src=\"". $result->link[1]->attributes()->href ."\" style=\"float: left;\"><p>". $result->content."</p><div style=\"clear:both;\"> </div>";
}
?>
.
.
Waiting for your response :)

You could poll for changes through javascript / ajax, by setting up a timer that calls a function in Test Class which returns a list of tweets. Example (using jquery because I am no javascript expert):
$(function() {
function fetchTweets() {
$.ajax({
url: "testclass.php",
success: function(data) {
// Replace contents of one element with data
}
}
setInterval(fetchTweets(), 60000);
}
