How to echo xml file in php

Question

How to print an xml file to the screen in php?

This is not working:

$curl = curl_init();        
curl_setopt ($curl, CURLOPT_URL, \'http://rss.news.y         


        

Answer 1

You can use HTTP URLs as if they were local files, thanks to PHP's wrappers

You can get the contents from an URL via file_get_contents() and then echo it, or even read it directly using readfile()

$file = file_get_contents('http://example.com/rss');
echo $file;

or

readfile('http://example.com/rss');

Don't forget to set the correct MIME type before outputing anything, though.

header('Content-type: text/xml');

This works:

<?php
$XML = "<?xml version='1.0' encoding='UTF-8'?>
<!-- Your XML -->
";

header('Content-Type: application/xml; charset=utf-8');
echo ($XML);
?>

The best solution is to add to your apache .htaccess file the following line after RewriteEngine On

RewriteRule ^sitemap\.xml$ sitemap.php [L]

and then simply having a file sitemap.php in your root folder that would be normally accessible via http://www.yoursite.com/sitemap.xml, the default URL where all search engines will firstly search.

The file sitemap.php shall start with

<?php
//Saturday, 11 January 2020 @kevin

header('Content-type: text/xml');
echo '<?xml version="1.0" encoding="UTF-8"?>';
?>
<urlset
      xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
            http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">

<url>
  <loc>https://www.yoursite.com/</loc>
  <lastmod>2020-01-08T13:06:14+00:00</lastmod>
  <priority>1.00</priority>
</url>


</urlset>

it works :)

Answer 4

Am I oversimplifying this?

$location = "http://rss.news.yahoo.com/rss/topstories";
print file_get_contents($location);

Some places (like digg.com) won't allow you to access their site without having a user-agent, in which case you would need to set that with ini_set() prior to running the file_get_contents().

Answer 5

Here's what worked for me:

<pre class="prettyprint linenums">
    <code class="language-xml"><?php echo htmlspecialchars(file_get_contents("example.xml"), ENT_QUOTES); ?></code>
</pre>

Using htmlspecialchars will prevent tags from being displayed as html and won't break anything. Note that I'm using Prettyprint to highlight the code ;)

If you just want to print the raw XML you don't need Simple XML. I added some error handling and a simple example of how you might want to use SimpleXML.

<?php 
$curl = curl_init();        
curl_setopt ($curl, CURLOPT_URL, 'http://rss.news.yahoo.com/rss/topstories');   
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);   
$result = curl_exec ($curl);   

if ($result === false) {
    die('Error fetching data: ' . curl_error($curl));   
}
curl_close ($curl);    

//we can at this point echo the XML if you want
//echo $result;

//parse xml string into SimpleXML objects
$xml = simplexml_load_string($result);

if ($xml === false) {
    die('Error parsing XML');   
}

//now we can loop through the xml structure
foreach ($xml->channel->item as $item) {
    print $item->title;   
}
