What is the difference between the wampsever online mode and the offline mode?

We often use the wampsever server when developing websites. During the test project, we often find that both the online and offline modes of the wampsever server can be used and tested, another phenomenon is that we are testing wireless networks. When using mobile phones to access projects in the computer, only the wampsever online mode can access projects in the computer through the lan. What is the difference between the two?

Wampsever online mode: Apache can be accessed on the local machine or other machines, that is, your WEB server can be accessed using the actual IP address.

Wampsever offline mode: only the local machine can access Apache, and only localhost or 127.0.0.1 can be used.

# Onlineoffline tag-don't remove Order Deny, Allow Deny from all Allow from 127.0.0.1
