Also, let me mention the method of resolving the domain name to the local (Windows system):
Use Notepad to open the system disk (c:) Windows/system32/drivers/etc/hosts file
You can do it in the last line See something like: 127.0.01 localhost
It’s easy to see at a glance. Accessing localhost will directly access 127.0.01, which is local
Then just copy one and correct the localhost to your own project domain name, such as: myweb.com Save
Open phpstudy-》More options menu-》Site domain name management-》Fill in the information, change the domain name to the same domain name as above, and the directory to your own project directory
The port remains unchanged, save and restart to take effect, now type myweb directly in the browser. com directly to your local server project!
