If I want to write the first parameter sent to the client, how can I write it?

Reply to discussion (solution)

$ Client = socket_accept ($ this-> master); // 27 rows

$ Bytes = @ socket_recv ($ socket, $ buffer, 2048,0) of 36 rows; receives data sent by the client.
47 when $ this-> send ($ socket, $ buffer); is to send data to the client

This is a test program that only sends data from the client as it is. Far from Practical use
You need to write a program to analyze and process the data sent by the user.
Return the corresponding data based on the processing result.
This program needs to be called between lines 46 and 47.

Is there any practical code? I have been searching for the code for a day. I don't see any reliable problems. as long as the client sends a and the server receives the data. if it is a, it returns a as it is.

Isn't your program like this?

The problem is that your client

The client I wrote in c ++. now I am writing to the server.

Then you downloadAndroid and PHP development best practices source code. The Download channel is available.
I have published a book. it should be okay.
