检查页面在打开和关闭PHP标记之前或之后是否包含空格。删除这些空格。您可以发布错误页面的内容吗？标题之前没有输出，这怎么不清楚？错误消息是错误页面上显示的唯一文本吗？是否显示了其他错误/警告？我得到了类似的答案，直到有人告诉我contact.php（一个成熟的html页面）包含在index.php（另一个完整的html页面）的主体中。设置contact.php中的标题时index.php已经刷新了一半。我没有完全理解您所说的，但是。。。它帮助我在几分钟内制定出一个有效的解决方案。谢谢我曾尝试从contact.php中删除和元素，但这并不能解决问题。我最后做的是将contact.php的整个部分添加到index.php中，并将其添加到index.php中，以替换以前的内容。然后，我从contact.php中删除了and元素，但以与以前相同的方式将其链接到index.php。这彻底解决了问题。非常感谢。在成为一名合法的web开发人员并学习了PHP之后，我可以说，做我想做的事情的最好方法就是使用嵌入联系人表单。这非常简单，而且是最干净的方法。
