当url字符串是现有文件的名称时，mod_rewrite不起作用

Question

What I want to do is to remove the php file extension needed for the url,

ie myipaddress/abc -> myipaddress/abc.php

However I can't seem to get mod_rewrite to work using the solutions in this link .

My .htaccess file contains these lines:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
#RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*)$ $1c.php [L]

So if i have a file named abc.php on my server and my url in the browser is "myipaddress/ab", abc.php will be properly shown. Any file that cannot be found will return me a internal server error (since the third cond is commented out).

In this case i get this to work:

myipaddress/ab -> myipaddress/abc.php

Now if i change the last line like this (which is the answer provided):

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
#RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*)$ $1.php [L]

Now if I have a file named abc.php and i put in myipaddress/abc, i get a 404 not found which says

Not Found

The requested URL /abc was not found on this server.

If i look up for other links like abcd.php which is not on my server, i still get a 500 internal server error. However when i try a link like myipaddress/name and if name.php is on my server, i get a 404. I'm very confused by the fact that if the url contains name, mod_rewrite will not rewrite the url and have spent hours on it. Can anyone help?

Sounds like you have automatic content negotiation enabled on your system. You want to disable it.

Take a look into the documentation. It is well written and comes with lots of great examples:
