php - Allow someone else to connect to my XAMPP mysql

Solution:

It creates tunnels to localhost, but it has no custom domains on the free plan though.

Solution:

Use ngrok. Alternatively if you want it to be free in terms of use, you can setup your own ngrok like server using expose. Here is the link https://github.com/beyondcode/expose
