How to compose (configure) RewriteCond for .htaccess?

Question

Apache HTTP Server

Good day everyone!
Please help me compose a RewriteCond for .htaccess
, how to do it so that at the end of the address index.php is removed (if it exists), example:

sitename.ru/.../index.php >> sitename.ru/.../
sitename.ru/index.php >> sitename.ru

after that there should be a redirect to the input file

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]

Answer 1

Try adding the following rule at the beginning:
RewriteRule ^(.*/)index\.php(.*) /$1$2 [L,R=301]
