Want to parse podcast feed in php

I want to get the audio and logo URLs for each episode of the podcast using php.

First I try to use simplepie to parse feed. But, it so complex for me. I only found how to get podcast episode's logo. but I can't find the way to get URL of the audio file from RSS.

Next I try to use the package link below. But when I try to use it, I get an error like that " Error Call to undefined function Lukaswhite\PodcastFeedParser\Parser().".

PS. If you are try for this. This repository's redme file is incorrect.

composer require lukaswhite/php-feed-parser

use this.

composer require lukaswhite/podcast-feed-parser
