regex online

Question

Estoy tratando de eliminar .php .html y trazando la barra desde url usando htaccess, sin embargo, este código funciona bien para php pero no para html y slash final

Para PHP

RewriteCond %{THE_REQUEST} ^GET.*index/.php [NC]
RewriteCond %{REQUEST_URI} !/system/.* [NC]
RewriteRule (.*?)index/.php/*(.*) /$1$2 [R=301,NE,L]
# Directs all EE web requests through the site index file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]

Para HTML

RewriteCond %{REQUEST_URI} index.html
RewriteRule ^(.*)index.html$ /$1/ [R=301,L]

Answer 1

Tenerlo de esta manera:

# externally redirect /dir/file.php to /dir/file and remove index
RewriteCond %{THE_REQUEST} /s/+(.*?/)?(?:index)?(.*?)/.(?:html?|php)/?[/s?] [NC]
RewriteRule ^ /%1%2 [R=301,L,NE]

# remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{THE_REQUEST} /s(.+?)/+[?/s]
RewriteRule ^(.+?)/$ /$1 [R=301,L]

# internally add php extension
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1.php -f
RewriteRule ^(.+?)/?$ $1.php [L]

# internally add html extension
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1.html -f
RewriteRule ^(.+?)/?$ $1.html [L]
