Problems downloading files in the Safari browser?

Question

safari

A known bug in Safari adds a .html extension when downloading a file. For example, if a .rar archive is downloaded, then .rar.html will be downloaded in Safari. PHP
site templates are not supported. So header("Content-Type: application/$file_type"); can't write.
It didn't help in .htaccess AddType application/x-httpd-php .html .htm
Setting the download attribute in links didn't help either.
Maybe someone had a similar problem, how did you solve it? Or what else is the solution without php?
