Question

如果所有查询都插入到数据库中，尝试重定向到另一个页面，但它不会重定向而是显示警告而不是重定向。

警告：无法修改标题信息 - 已在第249行的C：\ wamp64 \ www \ quiz \ quiz.php中发送的标题（输出从C：\ wamp64 \ www \ quiz \ quiz.php：183开始）< / p>

我的代码 :(代码从行开始：180直到EOF）

    <h1><?php echo $it; ?>)&nbsp;<?php echo $Question; ?></h1></br>

将PHP代码移至页面顶部，并在标题重定向语句后添加{{1}}。

所有HTML代码都追溯到以前的所有PHP代码。

在PHP中的“提交”按钮后重定向无法正常工作
