Remove and Redirect index.php from CodeIgniter – SEO

I got an old project and it has some bizarre issue. Its CodeIgniter project (version 2.X).

Google is indexing our URLs with index.php?. Below is an example

https://www.website.com/index.php?/my-seo-friendly-uri

I can see my pages from above url and with 2 more variants as below

https://www.website.com/index.php/my-seo-friendly-uri

https://www.website.com/my-seo-friendly-uri

We have used https://www.website.com/my-seo-friendly-uri throughout the site.

My question is how I can redirect https://www.website.com/index.php?/my-seo-friendly-uri and https://www.website.com/index.php/my-seo-friendly-uri to https://www.website.com/my-seo-friendly-uri?

The thing I already did

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^index.php/(.*)$ /$1 [R=302,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L] 
</IfModule>

This redirects index.php to normal URLs, but index.php? version of url is still not redirecting

In my config.php, I have the following settings

$config['index_page'] = '';
$config['uri_protocol'] = 'REQUEST_URI';

    https://www.example.com/index.php?/my-seo-friendly-uri

    This URL contains a query string and so requires a slightly different rule in order to match it. The RewriteRule pattern matches against the URL-path only (just index.php in this case). The query string is available in its own variable.

    Add the following, before your existing directives (in addition to the directive that matches /index.php/my-seo-friendly-url – which is passed as path-info):

    # Redirect URLs of the form "/index.php?/my-seo-friendly-uri"
# And "/?/my-seo-friendly-uri"
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^(/.*)
RewriteRule ^(index.php)?$ %1 [QSD,R=302,L]

    The query string is captured (2nd condition), and the backreference (%1) is used to construct the redirect.

    The first condition that checks against the REDIRECT_STATUS environment variable is required in order to prevent a redirect loop, since you appear to be using the query string method to route the codeigniter URLs in the later rewrite. The REDIRECT_STATUS env var is empty on the initial request, but set to “200” (as in 200 OK HTTP status) after the first successful rewrite.

    The QSD flag (Apache 2.4+) is required to discard the original query string from the redirected request. If you are still on Apache 2.2 then append a ? (empty query string) to the substitution string instead. ie. %1?

    By making the match for index.php optional (ie. ^(index.php)?$) it will also canonicalise URLs that omit index.php, but still include the query string (that may or may not currently be a problem). eg. /?/my-seo-friendly-uri.

    Note that this is currently a 302 (temporary) redirect (as is your existing redirect). Only change this to a 301 (permanent) redirect once you have confirmed it works OK. 301s are cached persistently by the browser so can make testing problematic.

    Summary

    Your .htaccess file should look like this:

    RewriteEngine On

# Query string...
# Redirect URLs of the form "/index.php?/my-seo-friendly-uri"
# And "/?/my-seo-friendly-uri"
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^(/.*)
RewriteRule ^(index.php)?$ %1 [QSD,R=302,L]

# Path-Info...
# Redirect URLs of the form "/index.php/my-seo-friendly-uri"
# Also handles "/index.php" only
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^index.php(?:/(.*))?$ /$1 [R=302,L]

# CodeIgniter Front-controller
# (NB: Using query string method to pass the URL)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) index.php?/$1 [L]

    Additional notes…

    • The <IfModule> wrapper is not required.
    • (.*) is the same as ^(.*)$ since regex is greedy by default.
    • I’ve modified your existing path-info redirect (ie. /index.php/foo) to also redirect requests for /index.php only. This now requires an additional condition to avoid a redirect loop.

    • Your CodeIgniter front-controller is using the query string method to pass /my-seo-friendly-url to the backend (as used in the question). However, you have set $config['uri_protocol'] = 'REQUEST_URI'; – which contradicts with this (although shouldn’t necessarily be a problem). However, if you are using the REQUEST_URI method then you can remove the ?/$1 part from the end of the final RewriteRule substitution string. For example:

      For example, from this:

      RewriteRule (.*) index.php?/$1 [L]

      To this:

      RewriteRule . index.php [L]

    Use .htaccess…………….

     <IfModule mod_rewrite.c>
 RewriteEngine on
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d

 <IfModule mod_php5.c>
     RewriteRule ^(.*)$ index.php/$1 [L]
 </IfModule>

 <IfModule !mod_php5.c>
     RewriteRule ^(.*)$ index.php?/$1 [L]
 </IfModule>

</IfModule>
