无法使用 simplexml_load_file() 访问 XML 文档 [英] Cannot access XML Document using simplexml_load_file()
问题描述
我需要帮助！我正在尝试从托管提供商的网站数据库中生成 XML 文档，并从我的家用 PC 访问它，现在我正在本地主机环境中执行此操作.我使用这些代码并在浏览器中收到错误消息.请看看我的代码...
I NEED HELP! I'm trying to generate XML document from my website database in hosting provider and accessing it from my home PC, right now I'm doing it in localhost environment. I use these codes and I got error message in browser. Please take a look at my codes...
data.php 用于生成 XML 文档
data.php for generating XML document
<?php
include ("koneksi-database.php");
header('Content-Type: text/xml');
echo "<?xml version='1.0'?>";
echo "<outbox>";
$query = "SELECT * FROM `tbstatus` WHERE `status` = '$status' ORDER BY `ID`";
$result = mysql_query($query);
while ($data = mysql_fetch_array($result))
{
echo "<data>";
echo "<trx>".$data['trx']."</trx>";
echo "<status>".$data['status']."</status>";
echo "<signature>".$data['signature']."</signature>";
echo "<time>".$data['time']."</time>";
echo "</data>";
}
echo "</outbox>";
?>
read.php 用于读取 localhost 中的 XML 文档
read.php for reading the XML document in localhost
print_r($dataxml = simplexml_load_file('data.php'));
我还创建了 index.php 以每 5 秒运行一次脚本.
I also create index.php for running the script every 5 seconds.
<html>
<head>
<script type="text/javascript">
var xmlhttp;
function ajax()
{
if (window.XMLHttpRequest)
{
xmlhttp=new XMLHttpRequest();
}
else
{
xmlhttp =new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
// do nothing
}
}
xmlhttp.open("GET","read.php");
xmlhttp.send();
setTimeout("ajax()", 5000);
}
</script>
</head>
<body onload="ajax();">
<h1>Server is Running...</h1>
</body>
</html>
最后这是我打开 read.php 时从浏览器收到的错误消息.
finally this the error messages that i get from browser when I open read.php.
Warning: simplexml_load_file() [function.simplexml-load-file]: data.php:9: parser error : Start tag expected, '<' not found in C:\xampplite\htdocs\simpul\baca.php on line 9

推荐答案
您的 print_r($dataxml = simplexml_load_file('data.php')); 正在读取原始 PHP 文件，而不是脚本执行结果！
Your print_r($dataxml = simplexml_load_file('data.php')); is reading you raw PHP file, not the script execution result!
data.php 文件包含输出 XML 文件的 PHP 代码，而不是真正的 XML 文件.
data.php file have a PHP code that outputs a XML file, not a really XML file.
你应该使用 print_r($dataxml = simplexml_load_file('http://localhost/data.php')); 为例.(假设 http://localhost/data.php 是访问文件的 url.)
You should use print_r($dataxml = simplexml_load_file('http://localhost/data.php')); for example. (Assuming that http://localhost/data.php is the url to access your file.)
仅使用 'data.php' 作为参数将从服务器获取原始文件，而不是由 PHP 处理.
using only 'data.php' as parameter will get the raw file from server, not processed by PHP.
