.htaccess的PHP正则表达式

Question

Say I have a page testpage.php and I want to access it through localhost/testpage . I can't figure out the regex to get it to work.

When I use the following, I get a server error

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* "^[^0-9][A-z0-9_]+*.php"/$0 

However, when I specify the exact file it works.

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* testpage.php/$0 

Answer 1

Try this:

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

the third line checks if the file actually exists before doing the rewrite to avoid errors
