【问题描述】：

我正在尝试从 ebay api 中提取一些信息。我有这个链接 http://open.api.ebay.com/shopping?callname=GetMultipleItems&responseencoding=XML&appid=Morcovar-c74b-47c0-954f-463afb69a4b3&siteid=0&version=525&IncludeSelector=ItemSpecifics&ItemID=220617293997,250645537939,230485306218 并且我正在使用 SimpleXML 。到目前为止，我设法提取了我需要的所有信息，除了“PictureURL”。问题是当我打印到 simpleXMl 时，图片似乎在一个数组中

[GalleryURL] => http://thumbs4.ebaystatic.com/pict/1105372138158080_1.jpg [图片URL] => 数组 ( [0] => http://i.ebayimg.com/09/!Bt+mKZQCWk~$(KGrHqYH-CYEvrwcUC47BL-,(K(pnw~~_1.JPG?set_id=8800005007 [1] => http://i.ebayimg.com/01/!Bt+mDTwB2k~$(KGrHqUH-DEEvirheBYUBL-,WtytJQ~~_1.JPG?set_id=8800005007 [2] => http://i.ebayimg.com/22/!Bt+mE8!EGk~$(KGrHqUH-CMEvsjKcE3JBL-,Wzr+sw~~_1.JPG?set_id=8800005007 [3] => http://i.ebayimg.com/17/!Bt+mFg!EGk~$(KGrHqIH-DoEvp43,)33BL-,W14vYQ~~_1.JPG?set_id=8800005007 [4] => http://i.ebayimg.com/01/!Bt+mQ0!!2k~$(KGrHqIH-EQEvqDDLQZVBL-,(j1YGg~~_1.JPG?set_id=8800005007 [5] => http://i.ebayimg.com/01/!Bt+mSq!EGk~$(KGrHqQH-C4Evs(Rz(JWBL-,(rdtsw~~_1.JPG?set_id=8800005007 [6] => http://i.ebayimg.com/03/!Bt+mUBw!Wk~$(KGrHqEH-DEEvnQtM9VkBL-,(w1+lQ~~_1.JPG?set_id=8800005007 [7] => http://i.ebayimg.com/15/!Bt+mHKQEGk~$(KGrHqQH-E!Evlr98iwBBL-,W87Nug~~_1.JPG?set_id=8800005007 [8] => http://i.ebayimg.com/13/!Bt+mI3!Bmk~$(KGrHqMH-DkEvq1,F2ooBL-,(EQ7Vg~~_1.JPG?set_id=8800005007 [9] => http://i.ebayimg.com/05/!Bt+mL2gEWk~$(KGrHqIH-EYEvov7vQY4BL-,(PzCKQ~~_1.JPG?set_id=8800005007 [10] => http://i.ebayimg.com/24/!Bt+mNlwEWk~$(KGrHqIH-CYEvqPjh6RQBL-,(Wh+S!~~_1.JPG?set_id=8800005007 [11] => http://i.ebayimg.com/19/!Bt+mPE!!2k~$(KGrHqQH-CYEvr5z9)NVBL-,(c3bzw~~_1.JPG?set_id=8800005007 )

但是，如果我尝试从数组中获取它们，我不会得到任何结果。这是我目前拥有的代码

$items = "220617293997,250645537939,230485306218,110537213815,180519294810"; $number_of_items = count(explode(",", $items)); $xml = $baseClass->getContent("http://open.api.ebay.com/shopping?callname=GetMultipleItems&responseencoding=XML&appid=Morcovar-c74b-47c0-954f-463afb69a4b3&siteid=0&version=525&IncludeSelector=ItemSpecifics,description&ItemID=$items "); writeDoc($xml, "api.xml"); $getvalues = simplexml_load_file('api.xml'); $picture_url = $getvalue->Item[$number]->PictureURL[2]; echo "图片地址为$picture_url";

使用上面的代码，我期望从数组中提取第二张图片 url。提前感谢您的帮助！

【问题讨论】：

$getvalues 和 $getvalue 不同...
确实......这就是问题所在。

【解决方案1】：

恐怕无法对此进行测试，但是您是否尝试过 var_dump($picture_url) 来查看 $picture_url 是什么？也许它需要转换为字符串？

echo "picture url is" .  (string)$picture_url;
