index.php keep showing

[eluser]EEssam[/eluser]
Hello,

I'm coding in http://localhost/somefolder so I created a .htaccess file like the following:

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ ./index.php/$1 [L]

I copied that from CI docs, I just added the ./ on the last line, and it's working but the all the links are showing the index.php again! If I remove the index.php manually the links work as well.

So, why index.php is being added and how can I get rid of it forever?

Thanks.
