<?php
 $url = "https://anchor.fm/s/75abc654/podcast/rss";

        $invalidurl = false;
        if(@simplexml_load_file($url)){
            $feeds = simplexml_load_file($url);
        }else{
            $invalidurl = true;
            echo "<h2>Invalid RSS feed URL.</h2>";
        }
        $i=0;
        if(!empty($feeds)){

            $site = $feeds->channel->title;
            $sitelink = $feeds->channel->link;

            foreach ($feeds->channel->item as $item) {

                $title = $item->title;
                $link = $item->link;
                $description = $item->description;
                $mp3 = $item->enclosure['url'];
               // $season= $item->itunes:season;
                $image = $item->itunes->image->href;
                $postDate = $item->pubDate;
                $pubDate = date('D, d M Y',strtotime($postDate));


                if($i>=5) break;
        ?>

In this code $image = $item->image->href; doesn't get the image url.. I don't know how to get the image url, please help me to get the image URL. .. Thanks in advance

You are dealing with a namespaced node within the XML / RSS document so you should use the namespace to help identify the nodes of interest. I have never used simpleXML so can only offer an alternative solution that uses conventional DOMDocument and DOMXPath

As I say I have never used SimpleXML but I notice that there is XPath support for it so you could adapt the code below

The trick here is to register the appropriate namespace so that the XPath expression can use it.

$url='https://anchor.fm/s/75abc654/podcast/rss';
$dom=new DOMDocument;
$dom->load( $url );

$xp=new DOMXPath( $dom );
$xp->registerNamespace('itunes','http://www.itunes.com/dtds/podcast-1.0.dtd');


$img=$xp->query('//channel/itunes:image');
if( $img )echo $img->item(0)->getAttribute('href');

The above will simply output

https://d3t3ozftmdmh3i.cloudfront.net/production/podcast_uploaded_nologo/19641917/19641917-1637668693797-44b27f4c00a16.jpg

To expand upon the above slightly and register other namespaces that are used in the RSS feed and then query the DOM for namespaced elements perhaps the following will help clarify how you can work with namespaces. The $tags array is simply a random selection of elements from the source file that will be used to construct the XPath expression - some of which use the dc or atom namespace and some have none.

$url='https://anchor.fm/s/75abc654/podcast/rss';

$dom=new DOMDocument;
$dom->load( $url );

$xp=new DOMXPath( $dom );
$xp->registerNamespace('dc','http://purl.org/dc/elements/1.1/');
$xp->registerNamespace('itunes','http://www.itunes.com/dtds/podcast-1.0.dtd');
$xp->registerNamespace('atom','http://www.w3.org/2005/Atom');




$tags=array('title','description','author','link','atom:link','/item/title','/item/dc:creator','/item/pubDate','/item/itunes:summary');
foreach( $tags as $tag ){
    $expr=sprintf('//%s',$tag );
    $col=$xp->query( $expr );
    if( $col && $col->length > 0 ){
        foreach( $col as $node )printf('%s -> %s<br />',$tag,trim($node->nodeValue));
    }
}

This will print:
