Setting up .htaccess before hosting a site on the Internet

Question

htaccess

There is a simple website (product catalog), I am interested in competent .htaccess settings before placing the site on the Internet. Main questions:
1) Do I need to disable error output (php_flag display_errors off)? Is it better to do it in .htaccess or in some php file?
2) Access to which folders should be closed? The folder structure is simple - css, fonts, images, js, inc, templates.
3) What other settings are desirable?
And an additional question: is it worth turning off error output in this way:

ini_set('display_errors', 'Off');
error_reporting(0);

And where is the best place to do it?

Answer 1

I recommend the following settings in php.ini:

error_reporting = E_ALL
display_errors = Off
display_startup_errors = Off
log_errors = On
error_log = "<path_to_error_log_file>"

Close access to the inc and templates folders.
