Why does echoing htaccess-value end with file-ending? - .htaccess

Question

I have created an htaccess-file to hide file-endings and prettify URLs. Now trying out everything I witness echoing a value from a prettified URL shows the file-ending in the result.
This varied a lot as I wasn't sure where the problem is. So there was ([0-9a-zA-Z]+) for example. I have also tried solutions from StackOverflow.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]
RewriteRule ^events/([^/]+)$ viewevent.php?c=$1 [L,QSA]
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
And my viewevent.php-file
<?
echo $_GET["c"];
?>
I used to try different variations, but it's either error or with the file-ending. And the URL I enter is: url/events/bino.
I expect bino, but I get bino.php.
Where is the problem?

Answer 1

Your rules need more reordering otherwise in present state it will redirect http://example.com/events/foo to https://example.com/viewevent.php?c=foo thus exposing your internal handler.
Moreover you need to add .php for files that actually exist in your filesystem as php file.
You may use this code:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L,NE]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^events/([^/]+)/?$ viewevent.php?c=$1 [L,NC,QSA]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.+?)/?$ $1.php [L]

Answer 2

The answer was simple. Put RewriteRule ^([^\.]+)$ $1.php [NC,L] at the end of the file, else it's kind of mixing with the other rules.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^events/([^/]+)$ viewevent.php?c=$1 [L,QSA]
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
RewriteRule ^([^\.]+)$ $1.php [NC,L]
