Write blocking after phpsocket programming reading is complete

After phpsocket programming is read, write blocking socket tcp php server

The server code is as follows:

   
  
Client, the code is as follows:
  
    
If you replace the server-side client read operation with a circular internal read operation, the client will remain in the wait data status.
Is there a way for the server to write data to the client after reading it cyclically?

There is no error in this loop, but once the data is sent, the socket connection is closed. there is no need for a loop.

This is only a demo. in actual cases, the data sent by the client may not be long, so it can only be received cyclically.
 
  
       
The PHP_NORMAL_READ option should not be used in the read loop.
Removing PHP_NORMAL_READ does not solve the problem. Is there a solution?
 
  
While (true) {$ msg = socket_accept ($ socket); // accept a SOCKET if (! $ Msg) {echo "socket_accept () failed :". socket_strerror ($ msg ). "\ n"; break;} while (true) {$ command = strtoupper (trim (socket_read ($ msg, 1024); // wait for client data if (! $ Command) break; // related processing, such as directly returning socket_write ($ msg, $ command, strlen ($ command);} socket_close ($ msg ); if ($ command = "QUIT") // if the received message is break;} socket_close ($ socket); // Close the SOCKET

I use stream functions.

Good moderator
Here, I need to read the data analysis from the client before writing the data back to the client. if you want the client to send the quit command to end the socket, this online environment cannot be implemented. Is there a better way? Thank you !!
