PHP XML读取器超时？

我有以下用于访问我的网站内容的PHP脚本：

<?php
$con = mysqli_connect("x", "x", "x", "x");
// Check connection
if (mysqli_connect_errno())
{
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_query($con, "UPDATE products SET in_stock = 'no'");
$xml = new XMLReader;
$xml->open('compress.zlib://file.xml/compression/gzip/');
while ($xml->read())
{
    if ($xml->nodeType == XMLReader::ELEMENT)
    {
        if ($xml->name == 'merchant')
        {
            $merchant                  = array();
            $merchant['merchant_id']   = $xml->getAttribute('id');
            $merchant['merchant_name'] = $xml->getAttribute('name');
        }
    }
    if ($xml->nodeType == XMLREADER::ELEMENT)
    {
        if ($xml->name == 'prod')
        {
            $prod                  = array();
            $prod['merchant_id']   = $merchant['merchant_id'];
            $prod['merchant_name'] = $merchant['merchant_name'];
            $prod['aw_product_id'] = $xml->getAttribute('id');
            $prod['in_stock']      = $xml->getAttribute('in_stock');
        }

您是否先下载文件，然后对本地副本进行操作？否。。。我应该吗@哈克瑞斯。或者：如果没有，请不要怀疑错误消息。：）对于创建临时文件，这可能会有所帮助：；所以，只要我理解正确；如果我将文件保存在本地（解压），并使用与指向临时文件相同的代码，那么无论XML文档大小如何，我都不会再出现此错误了@是的。至少，如果您自己的磁盘上有XML，您可以实际看到它是XML。如果您也从磁盘打开一个文件，您不应该看到任何“HTTP请求失败！”错误。但是，下载文件时可能会看到这些。所以这里没有魔法，只是把失败的案例分开。
