Redirect http to https, non-www to www and "/index.php" to "/"

Question

Is this htaccess code the best/proper way to:

1. Send all http traffic to https
2. Send any visits to index.php to the URL that doesn't show "index.php"
3. Send all non-www traffic to www

This code works to do those things I mentioned, I just want to make sure it's the most proper/efficient way to do it and/or it's ordered correctly...

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteCond %{THE_REQUEST} ^.*/index.php 
RewriteRule ^(.*)index.php$ https://www.example.com/$1 [R=301,L] 
rewritecond %{http_host} ^example.com [nc]
rewriterule ^(.*)$ https://www.example.com/$1 [r=301,nc]

Answer 1

Keep your code consistent. If you are using RewriteRule, use the same capitalisation format in all declarations. Same for setting the flags (R, L, NC etc.); or the variables and so on.

I personally prefer to give an extra newline between any new set of RewriteCond segment, so that I would be able to easily identify groups later on. As well as, adding comments never hurt anybody.

Prefer to handle the requests/paths at as late stage as possible.

Lastly, if you have just one domain name to handle; you can merge the https and naked-domain rules in a single one. The final ruleset would be:

RewriteEngine On

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

RewriteCond %{THE_REQUEST} ^.*/index\.php [NC]
RewriteRule ^(.*)index\.php$ https://www.example.com/$1 [R=301,L]
