WordPress 404.php 301重定向但排除一个目录

Question

I use the following code in 404.php file, to redirect all 404 errors to home page

<?php
header("HTTP/1.1 301 Moved Permanently");
header("Location: ".get_bloginfo('url'));
exit();
?> 

Now, I want to exclude from this redirection a directory called guest How can I do that? Thank you!

The solution:

$url = 'https://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];

if (strpos($url,'guest') == false) {
       header("HTTP/1.1 301 Moved Permanently");
header("Location: ".get_bloginfo('url'));
    exit();
} else {
}
