[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??

回答1:

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

回答2:

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.
