最近，我得到了一些帮助修改我的.htaccess文件来隐藏PHP扩展的URL。当我得到它的工作，一些错误发生与我的网站。无论出于何种原因，在子目录中的任何PHP页面返回404错误。例如：

Recently, I got some help modifying my .htaccess file to hide the .php extension in the url. After I got it working, a few bugs occurred with my site. For whatever reason, any php page in a sub directory returns a 404 error. For example:

mywebsite.com/test/test.php（这个404的）

mywebsite.com/test/test.php (this 404's)

但

mywebsite.com/test/test.html（这工作就好了）

mywebsite.com/test/test.html (this works just fine)

由于这只是开始发生我的.htaccess文件被修改后，我假设问题在于那里。该文件包含如下：

Since this only started occurring after my .htaccess file was modified, I am assuming the problem lies there. The file contains as follows:

RewriteEngine On

# Unless directory, remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ http://www.mywebsite.com/$1 [R=301,L]

# Redirect external .php requests to extensionless url
RewriteCond %{REQUEST_METHOD} !POST
RewriteCond %{THE_REQUEST} /.+?.php [NC]
RewriteRule ^(.+?).php$ /$1 [R=301,L,NE]

# Resolve .php file for extensionless php urls
RewriteRule ^([^/.]+)$ $1.php [L]

ErrorDocument 404 /404.php

DirectoryIndex index.php

如果有任何更多的信息，我可以提供，以帮助解决这个问题，请让我知道！

If there is any more information I can provide to help solve this, please let me know!

感谢您的所有帮助。

推荐答案

在你的根目录的.htaccess尝试这些规则：

Try these rules in your root .htaccess:

ErrorDocument 404 /404.php    
DirectoryIndex index.php
RewriteEngine On
RewriteBase /

# Unless directory, remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ /$1 [R=301,L,NE]

# Redirect external .php requests to extensionless url
RewriteCond %{REQUEST_METHOD} !POST
RewriteCond %{THE_REQUEST} /.+?.php [NC]
RewriteRule ^(.+?).php$ /$1 [R=301,L,NE]

# Resolve .php file for extensionless php urls
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1.php -f [NC]
RewriteRule ^(.+?)/?$ $1.php [L]
