我试图开发一个搜索系统,我有一个问题..
我在同一目录中有一个index.php文件和一个search.php文件,我希望当用户在搜索字段中写入并提交时我想转到我的搜索页面.
但是我不明白发生了什么,因为我转到这个页面:localhost/project/tpl/search /但是一切都是白色的,我没有错误,但没有显示我的"search.php"文件的背景!
我尝试过:header('Location: http://localhost/project/tpl/search/');但我有同样的问题!
那里有人知道可能会发生什么?

if(isset($_POST['search']))
{
$search = $_POST['s'];
$search = setUri($search);

我的项目文件夹在htdocs中,我的项目文件夹是这样的:

然后search.php在tpl文件夹中,如下所示:

可能是一个简单的问题,但我在延迟请求处理函数中的输出时遇到问题.当我执行我的模板而不是响应编写器时,我正在使用"bufio"写入,但似乎缓冲区只能在它吐出来之前保持这么多.我担心它会吐出部分页面,然后遇到错误,留下不完整和难以理解的响应.什么是确保一切都保持缓冲直到它准备好被释放到野外的最佳策略?
我该如何解决此错误:
