示例 URL http://catalog.viglink.com/vigcatalog/products.xml?key=MY_KEY&keyword=samsung 内容如下所示: http: //pastebin.com/cLQ0guuV

我只能到这里

<?php
DEFINE (VIGLINK_API_KEY,'YOUR_API_KEY',true);
function parsing_xml($url){
    libxml_use_internal_errors(1);
    $xml = simplexml_load_file($url);
    $data = json_decode(json_encode($xml),true);
    return $data;
}
function viglink_get_products($query){
    $url = 'http://catalog.viglink.com/vigcatalog/products.xml?key=' . VIGLINK_API_KEY . '&keyword=' . urlencode($query);
    $data = parsing_xml($url);
    return $data;
}

$data = viglink_get_products('dewalt');
echo '<pre>';
print_r($data);`

`

我想展示产品,xml 的价格。请帮我继续php?

你为什么用$data = json_decode(json_encode($xml),true);??

如果你想要一个 json 内容,那么你的 URL 应该是

http://catalog.viglink.com/vigcatalog/products.json?xxxx
                                                 ^
                                                 |+--- json not xml 

解决方案

$url = 'http://catalog.viglink.com/vigcatalog/products.json?key=YOUR_KEY&keyword=samsung';
$data = json_decode(file_get_contents($url));
foreach($data->resources->merchants->merchant as $merchant) {
    printf("%s \n", $merchant->name);
}

输出

Newegg.com 
Wireless Emporium 
TigerDirect 
.....
Pixmania 
pcRUSH.com 
Barnes & Noble 
MyGofer 

获得奖品

foreach($data->results->products->product as $product) {
    printf("%s ... %0.2f-%0.2f\n", substr($product->name,0,30), $product->price_min, $product->price_max);
}
