推荐答案

您需要确保在header标记之前不输出任何内容.由于它以前工作过，所以我认为在调用标头之前您没有回显任何东西是没有错误的，并且由于您没有看到输出，因此我假设它正在输出空白.在某些地方，某些空格和/或不可见字符可以潜入文件中:

You need to make sure you don't output anything before the header tag. Since it was working before, I assume it's not an error where you are echo'n stuff before the call to header, and since you see no output, I assume it is outputting white-space. There are a few places where some whitespace and/or invisible characters can sneak into a file:

将光标放在打开PHP标记(<? or <?php)之前，并按几次退格键，然后按Delete键删除<，然后重新键入<.这样可以确保在您的标题之前没有向浏览器输出任何不可见的字符.

Put the cursor before your opening PHP tag (<? or <?php) and hit backspace a few times, then hit delete to delete the < and then retype the <. That will make sure there are no invisible characters being output to the browser before your headers.

然后遍历该文件包含的所有文件，并执行相同的操作，并删除该文件末尾的所有?>.如果这些文件包含其他文件，请在其上重复此操作.

Then go through any files that are included by that file, and do the same thing, as well as delete any ?> that you have at the end of the file. If those files include any othe files repeat this on them.
