The following error occurs when the PHP page is refreshed normally for the first time but is refreshed for the second time.

Cancel @ socket_connect @ to check whether warning information exists.

It is estimated that it has been connected once.

Y
VB should be able to close the connection. if you don't know VB, check it out.

VB problems. Only one connection is accepted.

I can use VB to communicate with VB once.

But why does PHP and VB increase connections? Can't I continue sending data based on the original connection?

VB-> VB creat, connect only once
PHP is creat once every refresh, so there are many connections.

Alas, I don't know how to solve this problem.

I just want to make a function to receive data from the VB client after PHP is sent and save the data to the TXT file.

Everything else is simple. this connection cannot be solved.

You can't refresh the page. if you refresh the page once and wait for a server to execute it again, you should keep a persistent connection in the background.

This is your design architecture. What is the real problem you want to solve? Chat? Office?

Close the connection after receiving VB

I have added but it still does not work.

Look at the VB book by yourself. it seems that you have closed the entire socket. you should just close the connection.
When the socket is closed, bind/accept is disconnected.

I am also looking for related books today, but I have never found them yet.

My problem solved

Add a new listener under winsock1.Close and then configure winsock1.Listen.
