Question about phpstudy port number

Question

My operating environment is ready, but I cannot add the port number. Once I add it, the search page appears. I can still access it without adding it. Is this possible?

www.phpcms.com: 81, the browser cannot access it by adding 81, but it can be accessed normally without adding 81.

www.sina.com.com: 82, adding 82 will not work, it is normal if you don’t add it

Although the two pages do not add port numbers, they can be accessed are their own contents.

Do you need to worry about this?

You need to configure the listening port number
