1. Start the service

Php server.php

After startup, the cursor stops here and waits for other users to connect.

2. View the connection

Use the command netstat-an | grep port to see if the port is in Listening state

Netstat-an | grep 9501

(PS: note the IP address used by the server. If it is a 127.0.0.1 loopback address, the client can only use 127.0.0.1 to connect.)

3. Test the TCP server

A new window connects to the server using telnet

Telnet 127.0.0.1 9501

At this point, if you look at the machine that starts the service, you will find that there is data returned.

Php server.php > Client:Connect.

When returning to the client, enter hellp world and find that the write and read are successful

Root@iZ28evegw6zZ:~# telnet 127.0.0.1 9501 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is'^]'.
