Are there solutions or practices for redirecting a site to a mobile version of a site?

Question

PHP

Faced with the fact that our store needs to be adapted for mobile devices, it’s easier for me to create a mobile version on WordPress ,

but how to do it? so that when determining the php script, the device type is automatically transferred from www.example.ru (simple version) to www.m.example.ru (mobile wordpress)

What do you think about it and how to work with it - mobiledetect.net

Answer 1

The $_SERVER variable contains information about the user agent of the user. You can analyze this information, and, having determined that the user is sitting from a mobile browser, send him to www.m.example.ru

Answer 2

media in CSS and you don't have to redirect anything
