刚开始可以输出字符串。但是查看源文件是XML格式的
加了行header("Content-type:text/xml");
就提示
-----------------------
无法显示 XML 页。
使用 XSL 样式表无法查看 XML 输入。请更正错误然后单击 刷新按钮,或以后重试。
--------------------------------------------
XML 文档只能有一个顶层元素。处理资源 'http://localhost/getXML.php' 时出错。第 2 行,位置: 2
Warning: Cannot modify header information - headers already sent by (output started at C:\AppServ\www\ge...
------------------------
后来去掉了那个header("Content-type:text/xml");
结果反而又没字符串了
纠结的哥蛋疼哦
------解决方案--------------------
因为你输出的是xml, 查看源文件就能看到了。
------解决方案--------------------
是你加上 header("Content-type:text/xml"); 这后出现的
因为 在header前不能有什么的输出。
出这个错误是因为 header('Content-Type:text/html;');发送头之前不能有任何输出,空格也不行,你需要将header(...)之前的空格去掉,或者其他输出的东西去掉,或者把header 直接放到 程序最上面,保证没有什么输出。echo print_r var_dump 之类的输出形式
------解决方案--------------------
检查下代码。进行单步的调试和打印,来排查是哪里出现的问题。 给你看个 关于你那个错误的网上的一些解决方法。http://hi.baidu.com/xiaefun/blog/item/87fd5f82e96a3eaa0df4d2cb.html
------解决方案--------------------
我也碰到过这问题。问题一般出现在以下几点
1、去除BOM
2、不能出现除了XML外的其它字符
3、4、?>结束之后也不能有换行甚至一个空格
------解决方案--------------------
菜单栏-格式- 以UTF-8 无BOM格式编码
------解决方案--------------------
恩。。跟你一样
------解决方案--------------------
------解决方案--------------------
你上面的代码是没问题的。你肯定是编码搞错了。

How to handle XML and JSON data formats in C# development requires specific code examples. In modern software development, XML and JSON are two widely used data formats. XML (Extensible Markup Language) is a markup language used to store and transmit data, while JSON (JavaScript Object Notation) is a lightweight data exchange format. In C# development, we often need to process and operate XML and JSON data. This article will focus on how to use C# to process these two data formats, and attach

Use PHPXML functions to process XML data: Parse XML data: simplexml_load_file() and simplexml_load_string() load XML files or strings. Access XML data: Use the properties and methods of the SimpleXML object to obtain element names, attribute values, and subelements. Modify XML data: add new elements and attributes using the addChild() and addAttribute() methods. Serialized XML data: The asXML() method converts a SimpleXML object into an XML string. Practical example: parse product feed XML, extract product information, transform and store it into a database.

Using Python to implement data validation in XML Introduction: In real life, we often deal with a variety of data, among which XML (Extensible Markup Language) is a commonly used data format. XML has good readability and scalability, and is widely used in various fields, such as data exchange, configuration files, etc. When processing XML data, we often need to verify the data to ensure the integrity and correctness of the data. This article will introduce how to use Python to implement data verification in XML and give the corresponding
