这是我的提要网址，它永远不会在浏览器中打开或需要数小时才能打开。

我想创建 PHP 页面，我想在我的 PHP 页面中放置一个搜索框（我将放置的位置），一旦点击提交，我的 PHP 代码应该搜索并显示相应的产品价格。

那么我应该为此或任何其他建议使用 SimpleXML 吗？

我建议使用XMLReader类，因为它不需要一次将完整的 xml 加载到内存中。

缺点是您必须手动实现搜索和过滤，对于简单的名称搜索，您可以执行以下操作：

$reader = new XMLReader;
$reader->open('shoppingcom.xml');

while ($reader->read()) {
    if ($reader->name == 'Product') {
        $productxml = $reader->readOuterXML();
        while ($reader->read()) {
            if ($reader->name == 'ProductName' && stristr($reader->readInnerXML(), 'adidas')) {
                print $productxml;
                // now it contains the <Product>...</Product> fragment of the xml
                // you can use simplexml on this fragment, or just add an if for Prize node
            }
            if ($reader->name == 'Product' && $reader->nodeType == XMLReader::END_ELEMENT) {
                break;
            }
        }
    }
}

尽管如此，示例提要是可靠的64M，如果您为此创建一个数据库，该数据库可以索引您要搜索的字段并返回 xml 片段，您可能会获得更好的实时搜索结果，因此您不必将所有内容标准化为表.
