解析器错误：字符串未开始期待 '或“在 PHP 中

Question

将 XML 文件转换为关联数组，

$xmlUrl = '../products.xml';
$xmlStr = file_get_contents($xmlUrl); 
$xmlObj = simplexml_load_string($xmlStr);  print_r ($xmlObj);exit;
$arrXml = objectsIntoArray($xmlObj);

您好，我正在尝试使用以下代码和包含以下内容的 Product.xml

<?xml version="1.0" encoding="utf-8"?>
<products>
  <product>
    <sku>p750h3</sku>
    <category>Plans: Vodafone Unlimited Cap</category>

我一整天都在尝试解决此问题并通过网络搜索解决方案，但我无法得到 。请告诉我原因？

Answer 1

这可能是由于 magic_quotes_runtime 在调用 file_get_contents 时添加反斜杠造成的。尝试以下操作：

$xmlUrl = '../products.xml';
$xmlStr = file_get_contents($xmlUrl); 
if (get_magic_quotes_runtime())
{
    $xmlStr = stripslashes($xmlStr);
}
$xmlObj = simplexml_load_string($xmlStr);  print_r ($xmlObj);exit;
$arrXml = objectsIntoArray($xmlObj);    $xmlStr = file_get_contents($xmlUrl);

或者，您可以通过 .htaccess 在 PHP 配置中禁用 magic_quotes_runtime （尽管这可能会对脚本中的其他位置产生影响），或者在脚本顶部附近添加以下内容：

set_magic_quotes_runtime(false);

Answer 2

只是出于好奇，你为什么不使用 simplexml_load_file()< /a>?

Answer 3

您应该修复您的 XML 字符串，它无效。
如果您想保持 XML 不变并避免验证错误，请使用 simplexml_load_string() 的第三个参数来设置正确的选项，请参阅 http://php.net/manual/fr/function.simplexml-load-string.php 和 http://www.php.net/manual/fr/libxml.constants.php

顺便说一句，我不明白为什么显示带有转义引号的 XML，它是否在源文件中转义了？
