htaccess不好，有些网址有和没有扩展名

Question

What i need in my htaccess is the following:

• some urls without .php ( a few ) ( this is missing in the current htaccess)
• website always redirect to www if its without
• delete slashes if no directory ( thats working now )

I'm trying all day long, but i think its not in the right order... this is what i have:

  RewriteEngine On
    RewriteBase /
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^([^\.]*)(\.php)?(\?*)$ index.php/$1$3 [L,QSA]

    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\ /(.*)index\.php/?([^\?\ ]*)
    RewriteRule ^ /%1%2 [L,R=301]

Redirecting non-www to www with .htaccess

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L

Remove .php extensions

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