Displaying XML Data Stored in a PHP Variable

PHP
1

Hey, guys.

I’m currently trying to pull data from the Playstation 3’s PSN API and I’m not entirely sure what I’m doing.

Here is my code, saved as trophycount.php.

<?php 

$url = "http://www.psnapi.com.ar/ps3/api/psn.asmx/getPSNID";
$username = "vlastanovak"; 
        
$ch = curl_init();     
    
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_TIMEOUT, 15); 
curl_setopt($ch, CURLOPT_POSTFIELDS, "sPSNID=$username"); 
    
$data = curl_exec($ch); 
curl_close ($ch); 
    
echo $data;

?>

Here it is online. If you view the source you will see that the XML is being returned.

How can I display specific data from the XML feed?

Also, when I change the echo $data line to return $data, the source becomes blank?

Thanks in advance!

Take a look at the [FPHP]SimpleXML[/FPHP] class.

I’ve got it working to some degree:

<?php

$url = "http://www.psnapi.com.ar/ps3/api/psn.asmx/getPSNID";
$username = "vlastanovak";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 15);
curl_setopt($ch, CURLOPT_POSTFIELDS, "sPSNID=$username");

$data = curl_exec($ch);
curl_close ($ch);

echo $data;

$psninfo = new SimpleXMLElement($data);

echo $psninfo->ID;

?>

<ul>
	<li>PSN: <?php echo $psninfo->ID; ?></li>
	<li>Total Trophies: <?php echo $psninfo->Trophies->Total; ?></li>
	<li>Platinum: <?php echo $psninfo->Trophies->Platinum; ?></li>
	<li>Gold: <?php echo $psninfo->Trophies->Gold; ?></li>
	<li>Silver: <?php echo $psninfo->Trophies->Silver; ?></li>
	<li>Bronze: <?php echo $psninfo->Trophies->Bronze; ?></li>
</ul>

However, it won’t work unless I echo $data first (line 17). When I change it to return $data it fails to echo the contents of the unordered list. What am I doing wrong here?
