Remove index.php from custom webapp's URL

I’m not sure if it’s the correct area, but I want to share this information as I couldn’t find it anywhere.

If, like me, you where struggling to find out how to remove the index.php from the url of your custom webapp, what I mean, in other words, or by example is that:
Instead of https://mycustomwebapp.com/index.php/pageI want to obtain https://mycustomwebapp.com/page.

Here’s the solution

Go to /etc/nginx/conf.d/your_custom_webapp_url, open your_custom_webapp_url.conf.
Then under:

if ($scheme = http) {
    rewrite ^ https://$server_name$request_uri? permanent;
 }

Add this:

if (!-e $request_filename)
{
    rewrite ^(.*)$ /index.php?q=$1 last;
}

Be aware, I’m not an expert, to me it just works, but I’m sure if it’s optimal, or safe.

Eh by curiosity, can you elaborate what you mean by “remove the index.php from the url” ? o.O

@Toshiwoz
You don’t need to remove index.php from nginx configuration.
If you have to use an app under webapp which don’t need php. Go to /var/www/mywebapp/www/ and remove the index.html. Put your created page as index.html and it will run as you wanted.

If you want a php app then you need to put the php app in /var/www/mywebapp/www. The app should index.php in it.

Thanks for the question, I have updated the post in order to be clearer.
I don’t want someone accidentally remove the index.php file from whatever they’re using… LOL…

LOL, no, sorry, that’s not what I meant…
I want to remove it from the url, I was struggling to do that because I thought I had to modify the .htaccess file, but that had no effect.
