Here's some code I've used in the past to show RSS news feed on PHP websites.
Create a getrss.php file with the falling code.
<?php
//get the q parameter from URL
$q=strip_tags(trim($_GET["q"]));
//find out which feed was selected
if($q=="Google") {
$xml=("http://news.google.com/news?ned=us&topic=h&output=rss");
} elseif($q=="ZDN") {
$xml=("https://www.zdnet.com/news/rss.xml");
}elseif($q=="CNN") {
$xml=("http://rss.cnn.com/rss/cnn_topstories.rss");
}elseif($q=="NYT") {
$xml=("https://rss.nytimes.com/services/xml/rss/nyt/US.xml");
}elseif($q=="LAT") {
$xml=("https://www.latimes.com/local/rss2.0.xml");
}
$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);
//get elements from "<channel>"
$channel=$xmlDoc->getElementsByTagName('channel')->item(0);
$channel_title = $channel->getElementsByTagName('title')
->item(0)->childNodes->item(0)->nodeValue;
$channel_link = $channel->getElementsByTagName('link')
->item(0)->childNodes->item(0)->nodeValue;
$channel_desc = $channel->getElementsByTagName('description')
->item(0)->childNodes->item(0)->nodeValue;
//output elements from "<channel>"
echo("<p><a href='" . $channel_link
. "'>" . $channel_title . "</a>");
echo("<br>");
echo($channel_desc . "</p>");
//get and output "<item>" elements
$x=$xmlDoc->getElementsByTagName('item');
for ($i=0; $i<=2; $i++) {
$item_title=$x->item($i)->getElementsByTagName('title')
->item(0)->childNodes->item(0)->nodeValue;
$item_link=$x->item($i)->getElementsByTagName('link')
->item(0)->childNodes->item(0)->nodeValue;
$item_desc=$x->item($i)->getElementsByTagName('description')
->item(0)->childNodes->item(0)->nodeValue;
echo ("<p><a href='" . $item_link
. "'>" . $item_title . "</a>");
echo ("<br>");
echo ($item_desc . "</p>");
}
On the page you want to display the news feeds add this to the header section.
<script>
function showRSS(str) {
if (str.length==0) {
document.getElementById("rssOutput").innerHTML="";
return;
}
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
} else { // code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function() {
if (this.readyState==4 && this.status==200) {
document.getElementById("rssOutput").innerHTML=this.responseText;
}
}
xmlhttp.open("GET","getrss.php?q="+str,true);
xmlhttp.send();
}
</script>
Then add a select box to the same page.
<form>
<select class="form-select" onchange="showRSS(this.value)">
<option value="">Select News</option>
<option value="Google">Google News</option>
<option value="ZDN">ZDNet News</option>
<option value="CNN">CNN Top Stories</option>
<option value="NYT">New York Times</option>
<option value="LAT">Los Angeles Times</option>
</select>
</form>
<div id="rssOutput"></div>
