htaccess rewrite rule to hide actual file - .htaccess

Question

This is my folder structure
htdocs
-> testing
->index.php
->.htaccess
Inside index.php I have this code
<?php
if(isset($_SERVER['PATH_INFO'])) {
echo $_SERVER['PATH_INFO'];
}
?>
Inside .htaccess I have this code
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ index.php/$1 [NC,L]
Here is my question:
In the above htaccess rewrite rule, which will link my address localhost/testing/HelloWorld to localhost/testing/index.php/HelloWorld
Is it possible to do some thing like this? When the user enter localhost/testing/index.php/HelloWorld I want the browser to hide the word index.php and only display something like this localhost/testing/HelloWorld
I tried to redirect the link localhost/testing/index.php/HelloWorld to localhost/testing/HelloWorld by adding another rule in .htacces file but I get "The webpage has redirect loop" error message.
After I add in new rule the .htacces file looks like this
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ index.php/$1 [NC,L]
RewriteCond %{REQUEST_FILENAME} -f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^index.php/(.+)$ /testing/$1 [R]
Does any ways that I could make my link like this? Thanks in advanced, your help will be very much appreciated.

Answer 1

You get the redirect loop, because the rewritten url matches the rule for redirection. You'll need to use a trick to make the external redirect only happen on an external request with index.php, not on an internal rewrite that maps a different request to that file. You can do this with %{THE_REQUEST} which will only ever be whatever the external request was. It will not update if you rewrite the file it maps to.
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ index.php/$1 [NC,L]
RewriteCond %{REQUEST_FILENAME} -f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{THE_REQUEST} ^(GET|POST)\ /testing/index\.php/
RewriteRule ^index.php/(.+)$ /testing/$1 [R]
