htaccess rewrite url redirect php file to folder

Question

I want to redirect this php url to the folder.

I always used the settings below. But since the update of apache to 2.4 it doesnt work anymore.

Goal: example.com/about.php?sub=about or example.com/about.php?sub= should be seen in the browser as example.com/about/

I use the following settings.

Options +FollowSymlinks
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^(example.com)(:80)? [NC]
RewriteRule ^(.*) http://www.example.com/$1 [R=301,L]
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://www.example.com/$1/ [L,R=301] 

RewriteRule ^about/$ about.php$1 [L]
RewriteRule ^about/([A-Za-z0-9-]+)$ about.php?sub=$1 [L]

This is what I am using now...

Answer 1

I don't see any rule in your code that is making /about.php?sub= to /about .

Try this code:

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+(about)\.php(\?sub=[^\s&]*)?\s [NC]
RewriteRule ^ /%1? [R=301,L]

RewriteRule ^about/?$ about.php?sub=about [L,NC,QSA]
RewriteRule ^about/([a-z0-9-]+)/?$ about.php?sub=$1 [L,NC,QSA]

# Add trailing slash
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule [^/]$ %{REQUEST_URI}/ [L,R]
