.htaccess: removing index.php from URL, force non-www and https - php

Question

I have below code in .htaccess file:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]
In general index.php is not there in URL. But, when I tried to add www infront of URL. It comes up with index.php file.
e.g.
https://example.com/settings/update_rates
After adding www infront of URL:
https://example.com/index.php?/settings/update_rates
How can I remove index.php here.

Answer 1

use this .htaccess
### Canonicalize codeigniter URLs
# Enforce SSL https://www.
RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
###
# Removes access to the system folder by users.
# Additionally this will allow you to create a System.php controller,
# previously this would not have been possible.
# 'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
# Checks to see if the user is attempting to access a valid file,
# such as an image or css document, if this isn't true it sends the
# request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

Following is the ideal .htaccess file for Codeigniter.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
### Canonicalize codeigniter URLs
# If your default controller is something other than
# "welcome" you should probably change this
RewriteRule ^(welcome(/index)?|index(\.php)?)/?$ / [L,R=301]
RewriteRule ^(.*)/index/?$ $1 [L,R=301]
# Removes trailing slashes (prevents SEO duplicate content issues)
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/$ $1 [L,R=301]
# Enforce www
# If you have subdomains, you can add them to
# the list using the "|" (OR) regex operator
RewriteCond %{HTTP_HOST} !^(www|subdomain) [NC]
RewriteRule ^(.*)$ http://www.domain.tld/$1 [L,R=301]
# Enforce NO www
#RewriteCond %{HTTP_HOST} ^www [NC]
#RewriteRule ^(.*)$ http://domain.tld/$1 [L,R=301]
###
# Removes access to the system folder by users.
# Additionally this will allow you to create a System.php controller,
# previously this would not have been possible.
# 'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
# Checks to see if the user is attempting to access a valid file,
# such as an image or css document, if this isn't true it sends the
# request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
# Without mod_rewrite, route 404's to the front controller
ErrorDocument 404 /index.php
</IfModule>
After this goto /system/application/config/config.php
and then find following line
$config['index_page'] = "index.php";
Make it as following
$config['index_page'] = "";
Because you are using Apache mod_rewrite, the above will set your config file so that “index.php” will NOT show up as part of the URL

You should give this try. I like to put my external redirects first. Also you can combine those rules by using your domain name. There is no point to using a wildcard unless you used this across many domains.
RewriteEngine On
RewriteCond %{HTTPS} !^on [OR]
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteRule ^(.*)$ https://example.com/$1 [R=301,L]
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
Then in your config.php file make sure you have already removed index.php.
Find below code:-
$config['index_page'] = 'index.php';
Replace with the below code:-
$config['index_page'] = '';
