解决方案：
with @ Mihai Iorga code i added ob_start （）;
这是因为您有输出：
>？;
<？php
会导致空行输出。
header（）必须在发送任何实际输出之前被调用，通过普通的HTML标签，文件中的空行或PHP发送
合并您的所有PHP代码，并确保在文件开头处没有任何空格。
也位于<$ c之后$ c> header（'location：index.php'）; add exit（）; 如果你有其他脚本在下面：
如果 i have this code,why my header location not working?
its a form of updating and editing and deleting some pages in my control panel...and i have an index.php file in the same folder of form.php...any help please?()i tryed to put the header after the editing and deleting...and still go to the form page not the index... solved:
with @ Mihai Iorga code i added ob_start(); That is because you have an output: results in blank line output. header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP Combine all your PHP codes and make sure you don't have any spaces at the beginning of the file. also after Also move your redirect header after the last 这篇关于标题位置不工作在我的PHP代码的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
，也可以在最后一个之后移动重定向页眉。<?php
