Can't read XML with simplexml_load_file PHP - php

Question

So i am trying to parse data from an XML url and insert it into a table using php, which can be seen here, (please keep in mind there are more products than displayed on this page, i am not trying to get it for just this Product,the code below shows how i am parsing all products) but i keep getting the following errors:
[EDITED]
class DataGrabber {
//The URL where data will be extracted from, which is an XML file
protected $URL = "http://json.zandparts.com/api/category/GetCategories/44/EUR/";
public function call_api($data) {
if(count($data) == 0) return array();
$jsondata = array();
foreach($data as $entry){
$url = $this->URL . $entry['model'] . "/" . urlencode($entry['family']) . "/" . urlencode($entry['cat']) . "/" . $entry['man'] . "/null";
$json = file_get_contents($url);
$data = json_decode($json, true);
if(!empty($data['Products'])){
foreach ($data['Products'] as $id => $product) {
$jsonentry = array(
'productnumber' => $id,
'partnumber' => $product['strPartNumber'],
'description' => $product['strDescription'],
'manu' => $product['Brand']
);
$jsondata[] = $jsonentry;
}
}
}
return $jsondata;
}
}
[NEW ERRORS]
So i have fixed the error:
PHP Warning: file_get_contents(http://json.zandparts.com/api/category/GetCategories/44/EUR/ET10B/E Series/AC Adapter/Asus/null): failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request
in /home/svn/dev.comp/Asus.php on line 82
by using urlencode as shown in my code above
This warning below isnt finding the values for the url:
PHP Warning: file_get_contents(http://json.zandparts.com/api/category/GetCategories/44/EUR///04G265003580/Asus/null): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found
as you can see after, 44/EUR there are three forward slashes with no data?? How would i resolve this??

Answer 1

The remote server appears to use the Accept HTTP header to choose the output format. With PHP default options it sends back JSON instead of XML:
<?php
echo file_get_contents('http://json.zandparts.com/api/category/GetCategories/44/EUR/ET10B/E%20Series/AC%20Adapter/Asus/null');
... prints:
{"Categories":[{"Brand":null,"Fami...
To specify an Accept header you need to retrieve the data with some other function, e.g.:
<?php
$context = stream_context_create(
array(
'http' => array(
'header' => "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n",
)
)
);
echo file_get_contents('http://json.zandparts.com/api/category/GetCategories/44/EUR/ET10B/E%20Series/AC%20Adapter/Asus/null', false, $context);
... prints:
<?xml version="1.0" encoding="utf-8"?><ProductCategory ...
Tweak it to your exact needs, I just copied the header from my browser.

Here's a code snippet that shows you how to get the values for strPartNumber, strDescription and Brand for all the products in that JSON data:
<?php
$url = 'http://json.zandparts.com/api/category/GetCategories/44/EUR/ET10B/E%20Series/AC%20Adapter/Asus/null';
$json = file_get_contents($url);
// Decode the JSON data as a PHP array
$data = json_decode($json, true);
if (!empty($data['Products'])) {
foreach ($data['Products'] as $id => $product) {
echo "Product #{$id}\n";
echo "Part number: {$product['strPartNumber']}\n";
echo "Description: {$product['strDescription']}\n";
echo "Brand: {$product['Brand']}\n\n";
}
}
Output:
Product #0
Part number: 04G265003580
Description: POWER ADAPTER 65W19V 3PIN
Brand: Asus
Product #1
Part number: 14G110008340
Description: POWER CORD 3P L:80CM,TW(B)
Brand: Asus
