How to parse xml in php?

When I started and learn php programming language. I have wanted to get data from xml file and read with php. I searched with Google. I got a lot of source codes. Some of codes are working in my local machine but when I upload and test it. It doesn’t work. I have found some codes are work with almost all of server. I will share it back.

Firstly, I have created example xml file as songs.xml like :

<?xml version="1.0" encoding="ISO-8859-1"?>

<currentsongs>
<song>
<title>Song Title One</title>
<artist>artist name</artist>

</song>

<song>
<title>Song Title Two</title>
<artist>Sec artist name</artist>

</song>
</currentsongs>

Then in php file :

<?php

$objDOM = new DOMDocument();
$objDOM->load("songs.xml"); //make sure path is correct

$songs = $objDOM->getElementsByTagName("song");

foreach( $songs as $value )
{
$title = $value->getElementsByTagName("title");
$song_title  = $title->item(0)->nodeValue;

$artist = $value->getElementsByTagName("artist");
$artist_name  = $artist->item(0)->nodeValue;

echo "$song_title - $artist_name <br>";
}

?>
