How to set .htaccess to specific condition?

Question

htaccess

My .htaccess in cms

<IfModule mod_rewrite.c>

# Enable rewrite rules
RewriteEngine on

# Base directory
RewriteBase /

# Deny direct access to .txt files
RewriteRule ^content/(.*)\.txt$ - [R=404,L]

# All URL process by index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*) index.php [PT,L]

## Application Handler
 #  RewriteCond %{REQUEST_FILENAME} !-d
 #  RewriteCond %{REQUEST_FILENAME} !-f
 #  RewriteRule ^(.*)?$ my.php [QSA,NC,L]

</IfModule>

I implemented my script in cms, I need to redirect to the
my.php file Above in the code, I have a commented , a working example, but if you uncomment it and leave the rules above - it does not work. I tried a bunch of options, either the site or my script works, they don’t want to work together. Please help create the correct .htaccess Thanks!
