Remove file extensions from urls

I've never used mod_rewrite but i want to remove all file extensions from my urls for a website. What is the rule that i would need to do this?

I've tried this, but that gives me an internal error every time i click a link on my website

RewriteRule ^(.*开发者_开发问答)$ $1.php [L]

Options +MultiViews is probably a better option for this. With that option enabled, Apache will intelligently rewrite the extension.

What you want to do is first check if the file exists, this will prevent the infinite loop that is causing the 500 error. It will also make other non-php file requests work (ie: images, css, etc).

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