Question

更新2015-08-09：
我更新了问题标题，以更加恰当地反映我的要求原始问题标题：
“将ebay完成api加载到simplexml_load_string（）中，但我要空了”
我还设法找到了下面给出的解决方案答案。

目前我正在尝试解析来自ebays的xml数据已完成列出api。
这一点有点棘手，因为我放入浏览器的网址返回xml 但是，当我使用simplexml_load_string并使用var_dump来查看它得到的内容时：bool（false）
有人可以帮我揭开我哪里出错或者问过这个问题，请指点我
我使用了$ obj = simplexml_load_file（）并收到了错误

simplexml_load_file(): I/O warning : failed to load external entity &quot;&quot;

我还使用了$ obj = new SimpleXMLElement（）和我收到的错误：

PHP Fatal error:  Uncaught exception 'Exception' with message 'String could not be parsed as XML'

我的代码如下：

的index.php

 $appleid= appID;

function CompletedItems($search, $categoryId)
{
    global $appid;
    $url ="http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findCompletedItems&SERVICE-VERSION=1.7.0&SECURITY-APPNAME=".$appid."&GLOBAL-ID=EBAY-GB&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&keywords=".$search."&CategoryID=".$categoryId."&itemFilter(0).name=SoldItemsOnly&itemFilter(0).value=true&sortOrder=PricePlusShippingLowest&paginationInput.entriesPerPage=1";
    $safeurl= urlencode($url);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $safeurl);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: text/xml'));
    $content = curl_exec($ch);
    $error   = curl_error($ch);
    curl_close($ch);

    $obj =  simplexml_load_string($content);

    echo"<h3>Completed Items</h3>";
    echo "Url: ".$url."<br>";
    var_dump($obj);

    return true;
}

我用以下函数调用该函数：CompletedItems（“iPod Touch第4代白色（8 GB）”，“73839”）;

我在加载页面时得到的响应：

Url: http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findCompletedItems&SERVICE-VERSION=1.7.0&SECURITY-APPNAME=AppID&GLOBAL-ID=EBAY-GB&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&keywords=Apple iPod Touch 4th Generation White (8 GB)&CategoryID=73839&itemFilter(0).name=SoldItemsOnly&itemFilter(0).value=true&sortOrder=PricePlusShippingLowest&paginationInput.entriesPerPage=1
bool(false)

但是，当我将链接粘贴到浏览器中时，我会收到：

Answer 1

我重写了我的代码，所以最终看起来像这样：

$appleid= appID;

function CompletedItems($search, $categoryId)
{
    echo"<h3>Completed Items</h3>";

    global $appid;
    $url = utf8_encode('http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findCompletedItems&SERVICE-VERSION=1.7.0&SECURITY-APPNAME='.$appid.'&GLOBAL-ID=EBAY-GB&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&keywords='.$search.'&CategoryID=".$categoryId."&itemFilter(0).name=SoldItemsOnly&itemFilter(0).value=true&sortOrder=PricePlusShippingLowest&paginationInput.entriesPerPage=2');
    $xml = simplexml_load_file($url);
    echo $url."<br>";

    if ($xml === false) 
        {
            echo "Failed loading XML: ";
            foreach(libxml_get_errors() as $error) 
                {
                    echo "<br>", $error->message;
                }
        } 
        else 
        {
            echo"<img class='wrap' src='".$xml->searchResult->item->galleryURL."'  alt='ebay image' >";
            echo "Item Id: ".$xml->searchResult->item->itemId."<br>";
            echo "Title: ".$xml->searchResult->item->title."<br>";
            echo "Global Id: ".$xml->searchResult->item->globalId."<br>";
            echo "Primary Catergory: ".$xml->searchResult->item->primaryCategory->categoryId.", ".$xml->searchResult->item->primaryCategory->categoryName ."<br>";
            // More Code can go here
        }

    echo"<br><br><br><br>";

    return true;
}

为什么simplexml_load_string（）返回为false？
